标准库（LSB）.第3-3部分:IA64（安腾TM）体系结构的桌面规范

[中文适用范围]： Linux标准基（LSB）定义了一个供编译应用程序使用的系统接口，并为安装脚本提供一个最小环境。其目的是为了在高体积应用中实现统一的行业标准环境。这些规范由两部分组成：一部分描述所有LSB实现中保持不变的部分，另一部分描述根据处理器架构变化的部分。共同部分和特定硬件架构的相关部分一起为共享同一硬件架构的系统上的编译应用程序提供完整的接口规范。LSB包含一组应用程序编程接口（API）和应用程序二进制接口（ABI）。API可能出现在可移植应用程序的源代码中，而编译后的程序二进制文件则可能使用更大的ABI集合。符合要求的实现必须提供此处列出的所有ABI。编译系统可能会通过宏定义等方式将某些API替换为对一个或多个底层二进制接口的调用，并在需要时插入对二进制接口的调用。LSB主要是一个二进制接口定义。并非所有可供应用程序使用的源级别API都包含在此规范中。这是Linux标准基（LSB）桌面模块的Itanium™架构特定部分。该部分通过补充那些因架构而异的接口，来补充LSB桌面模块的公共部分。该部分应与LSB桌面的公共部分一起使用。每当公共部分中的某一部分被架构特定信息补充时，公共部分会包含对该架构特定部分的引用。该部分还可能包含未在公共部分中引用的其他信息。在此LSB桌面部分描述的接口是强制性的，除非另有明确规定。在此LSB桌面模块中描述的接口是对LSB核心模块中描述的接口的补充，且不依赖于其他LSB模块。 [外文原描述]： 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.
