Linux Standard Base (LSB) — Part 3-3: Desktop specification for IA64 (Itanium TM) architecture

This document defines a system interface for compiled applications and a minimal environment for support of installation scripts. Its purpose is to enable a uniform industry standard environment for high-volume applications conforming to the LSB. These specifications are composed of two basic parts: a common part describing those parts of the interface that remain constant across all implementations of the LSB, and an architecture-specific part describing the parts of the interface that vary by processor architecture. Together, the common part and the relevant architecture-specific part for a single hardware architecture provide a complete interface specification for compiled application programs on systems that share a common hardware architecture. The LSB contains both a set of Application Program Interfaces (APIs) and Application Binary Interfaces (ABIs). APIs may appear in the source code of portable applications, while the compiled binary of that application may use the larger set of ABIs. A conforming implementation provides all of the ABIs listed here. The compilation system may replace (e.g. by macro definition) certain APIs with calls to one or more of the underlying binary interfaces, and may insert calls to binary interfaces as needed. The LSB is primarily a binary interface definition. Not all of the source level APIs available to applications may be contained in this specification. This is the Itanium™ architecture specific part of the Desktop module of the Linux Standard Base (LSB). This part supplements the common part of the LSB Desktop module with those interfaces that differ between architectures. This part should be used in conjunction with the common part of LSB Desktop. Whenever a section of the common part is supplemented by architecture-specific information, the common part includes a reference to the architecture-specific part. This part may also contain additional information that is not referenced in the common part. Interfaces described in this part of LSB Desktop are mandatory except where explicitly listed otherwise. Interfaces described in the LSB Desktop module supplement those described in the LSB Core module. They do not depend on other LSB modules.

ISO/IEC 23360-3-3:2021(E)
Introduction
The LSB defines a binary interface for application programs that are compiled
and packaged for LSB-conforming implementations on many different hardware
architectures. A binary specification must include information specific to the

computer processor architecture for which it is intended. To avoid the complexity

of conditional descriptions, the specification has instead been divided into
generic parts which are augmented by one of several architecture-specific parts,
depending on the target processor architecture; the generic part will indicate
when reference must be made to the architecture part, and vice versa.
This document should be used in conjunction with the documents it references.
This document enumerates the system components it includes, but descriptions
of those components may be included entirely or partly in this document, partly
in other documents, or entirely in other reference documents. For example, the
section that describes system service routines includes a list of the system
routines supported in this interface, formal declarations of the data structures
they use that are visible to applications, and a pointer to the underlying
referenced specification for information about the syntax and semantics of each

call. Only those routines not described in standards referenced by this document,

or extensions to those standards, are described in the detail. Information
referenced in this way is as much a part of this document as is the information
explicitly included here.
The specification carries a version number of either the form x.y or x.y.z. This
version number carries the following meaning:
1. The first number (x) is the major version number. Versions sharing the same
major version number shall be compatible in a backwards direction; that is,
a newer version shall be compatible with an older version. Any deletion of
a library results in a new major version number. Interfaces marked as
deprecated may be removed from the specification at a major version
change.
2. The second number (y) is the minor version number. Libraries and
individual interfaces may be added, but not removed. Interfaces may be
marked as deprecated at a minor version change. Other minor changes may
be permitted at the discretion of the LSB workgroup.

3. The third number (z), if present, is the editorial level. Only editorial changes

should be included in such versions.

Since this specification is a descriptive Application Binary Interface, and not a

source level API specification, it is not possible to make a guarantee of 100%
backward compatibility between major releases. However, it is the intent that

those parts of the binary interface that are visible in the source level API will

remain backward compatible from version to version, except where a feature
marked as "Deprecated" in one release may be removed from a future release.
Implementors are strongly encouraged to make use of symbol versioning to
permit simultaneous support of applications conforming to different releases of
this specification.
LSB is a trademark of the Linux Foundation. Developers of applications or
implementations interested in using the trademark should see the Linux
Foundation Certification Policy for details.

1 Scope
The Linux Standard Base (LSB) defines a system interface for compiled
applications and a minimal environment for support of installation scripts. Its
purpose is to enable a uniform industry standard environment for high-volume
applications conforming to the LSB.
These specifications are composed of two basic parts: a common part describing

those parts of the interface that remain constant across all implementations of the

LSB, and an architecture-specific part describing the parts of the interface that

vary by processor architecture. Together, the common part and the relevant
architecture-specific part for a single hardware architecture provide a complete
interface specification for compiled application programs on systems that share
a common hardware architecture.
The LSB contains both a set of Application Program Interfaces (APIs) and
Application Binary Interfaces (ABIs). APIs may appear in the source code of
portable applications, while the compiled binary of that application may use the
larger set of ABIs. A conforming implementation provides all of the ABIs listed
here. The compilation system may replace (e.g. by macro definition) certain APIs

with calls to one or more of the underlying binary interfaces, and may insert calls

to binary interfaces as needed.

The LSB is primarily a binary interface definition. Not all of the source level APIs

available to applications may be contained in this specification.
This is the Itanium™ architecture specific part of the Desktop module of the
Linux Standard Base (LSB). This part supplements the common part of the LSB
Desktop module with those interfaces that differ between architectures.
This part should be used in conjunction with the common part of LSB Desktop.
Whenever a section of the common part is supplemented by architecture-specific
information, the common part includes a reference to the architecture-specific

part. This part may also contain additional information that is not referenced in

the common part.
Interfaces described in this part of LSB Desktop are mandatory except where
explicitly listed otherwise. Interfaces described in the LSB Desktop module
supplement those described in the LSB Core module. They do not depend on
other LSB modules.

2.1 Normative References
The specifications listed below are referenced in whole or in part by the LSB
Desktop specification. Such references may be normative or informative; a

reference to specification shall only be considered normative if it is explicitly cited

as such. The LSB Desktop specification may make normative references to a

portion of these specifications (that is, to define a specific function or group of

functions); in such cases, only the explicitly referenced portion of the specification

is to be considered normative.

ISO/IEC 23360-3-3:2021(E)
Introduction
The LSB defines a binary interface for application programs that are compiled
and packaged for LSB-conforming implementations on many different hardware
architectures. A binary specification must include information specific to the

computer processor architecture for which it is intended. To avoid the complexity

of conditional descriptions, the specification has instead been divided into
generic parts which are augmented by one of several architecture-specific parts,
depending on the target processor architecture; the generic part will indicate
when reference must be made to the architecture part, and vice versa.
This document should be used in conjunction with the documents it references.
This document enumerates the system components it includes, but descriptions
of those components may be included entirely or partly in this document, partly
in other documents, or entirely in other reference documents. For example, the
section that describes system service routines includes a list of the system
routines supported in this interface, formal declarations of the data structures
they use that are visible to applications, and a pointer to the underlying
referenced specification for information about the syntax and semantics of each

call. Only those routines not described in standards referenced by this document,

or extensions to those standards, are described in the detail. Information
referenced in this way is as much a part of this document as is the information
explicitly included here.
The specification carries a version number of either the form x.y or x.y.z. This
version number carries the following meaning:
1. The first number (x) is the major version number. Versions sharing the same
major version number shall be compatible in a backwards direction; that is,
a newer version shall be compatible with an older version. Any deletion of
a library results in a new major version number. Interfaces marked as
deprecated may be removed from the specification at a major version
change.
2. The second number (y) is the minor version number. Libraries and
individual interfaces may be added, but not removed. Interfaces may be
marked as deprecated at a minor version change. Other minor changes may
be permitted at the discretion of the LSB workgroup.

3. The third number (z), if present, is the editorial level. Only editorial changes

should be included in such versions.

Since this specification is a descriptive Application Binary Interface, and not a

source level API specification, it is not possible to make a guarantee of 100%
backward compatibility between major releases. However, it is the intent that

those parts of the binary interface that are visible in the source level API will

remain backward compatible from version to version, except where a feature
marked as "Deprecated" in one release may be removed from a future release.
Implementors are strongly encouraged to make use of symbol versioning to
permit simultaneous support of applications conforming to different releases of
this specification.
LSB is a trademark of the Linux Foundation. Developers of applications or
implementations interested in using the trademark should see the Linux
Foundation Certification Policy for details.

1 Scope
The Linux Standard Base (LSB) defines a system interface for compiled
applications and a minimal environment for support of installation scripts. Its
purpose is to enable a uniform industry standard environment for high-volume
applications conforming to the LSB.
These specifications are composed of two basic parts: a common part describing

those parts of the interface that remain constant across all implementations of the

LSB, and an architecture-specific part describing the parts of the interface that

vary by processor architecture. Together, the common part and the relevant
architecture-specific part for a single hardware architecture provide a complete
interface specification for compiled application programs on systems that share
a common hardware architecture.
The LSB contains both a set of Application Program Interfaces (APIs) and
Application Binary Interfaces (ABIs). APIs may appear in the source code of
portable applications, while the compiled binary of that application may use the
larger set of ABIs. A conforming implementation provides all of the ABIs listed
here. The compilation system may replace (e.g. by macro definition) certain APIs

with calls to one or more of the underlying binary interfaces, and may insert calls

to binary interfaces as needed.

The LSB is primarily a binary interface definition. Not all of the source level APIs

available to applications may be contained in this specification.
This is the Itanium™ architecture specific part of the Desktop module of the
Linux Standard Base (LSB). This part supplements the common part of the LSB
Desktop module with those interfaces that differ between architectures.
This part should be used in conjunction with the common part of LSB Desktop.
Whenever a section of the common part is supplemented by architecture-specific
information, the common part includes a reference to the architecture-specific

part. This part may also contain additional information that is not referenced in

the common part.
Interfaces described in this part of LSB Desktop are mandatory except where
explicitly listed otherwise. Interfaces described in the LSB Desktop module
supplement those described in the LSB Core module. They do not depend on
other LSB modules.

2.1 Normative References
The specifications listed below are referenced in whole or in part by the LSB
Desktop specification. Such references may be normative or informative; a

reference to specification shall only be considered normative if it is explicitly cited

as such. The LSB Desktop specification may make normative references to a

portion of these specifications (that is, to define a specific function or group of

functions); in such cases, only the explicitly referenced portion of the specification

is to be considered normative.
