本文档定义了编译应用程序的系统接口和支持安装脚本的最小环境。其目的是为符合LSB的大容量应用提供统一的行业标准环境。 这些规范由两个基本部分组成:一个公共部分描述在LSB的所有实现中保持不变的接口部分，另一个特定于体系结构的部分描述因处理器体系结构而异的接口部分。单一硬件体系结构的公共部分和相关体系结构特定部分共同为共享公共硬件体系结构的系统上编译的应用程序提供了完整的接口规范。 LSB包含一组应用程序接口（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，而该应用程序的编译二进制文件可能使用更大的ABI集。一致性实现提供了此处列出的所有ABI。编译系统可以用对一个或多个底层二进制接口的调用替换（例如通过宏定义）某些API，并可以根据需要插入对二进制接口的调用。 LSB主要是一个二进制接口定义。并非所有应用程序可用的源代码级API都包含在本规范中。 这是Linux标准库（LSB）桌面模块中特定于PPC64体系结构的部分。 本部分使用不同体系结构的接口来补充LSB桌面模块的公共部分。 此部分应与LSB Desktop的公共部分结合使用。每当公共部分的某一部分补充了特定于体系结构的信息时，公共部分都包括对特定于体系结构的部分的引用。本部分还可能包含公共部分中未提及的其他信息。 除非另有明确列出，否则LSB Desktop本部分中描述的接口是强制性的。LSB桌面模块中描述的接口补充了LSB核心模块中描述的接口。它们不依赖于其他LSB模块。

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 PPC64 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.
