标准库（LSB）.第8-3部分:S390X体系结构的桌面规范

[中文适用范围]： Linux标准基础（LSB）定义了编译应用程序的系统接口和安装脚本支持的最小环境。其目的是为符合LSB的大批量应用程序提供一个统一的行业标准环境。 这些规范由两个基本部分组成：一个通用部分描述了在所有LSB实现中保持不变的接口部分，以及一个特定于体系结构的部分描述了随处理器体系结构变化的接口部分。通用部分和单个硬件体系结构的相关体系结构特定部分一起，为共享相同硬件体系结构的系统上的编译应用程序提供了一个完整的接口规范。 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，而该应用程序的编译二进制文件可能使用更大的ABI集。符合标准的实现提供此处列出的所有ABI。编译系统可能会用调用一个或多个底层二进制接口来替换某些API（例如，通过宏定义），并可能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。并非所有可用于应用程序的源级API都包含在此规范中。 这是Linux标准基础（LSB）桌面模块的S390X体系结构特定部分。这部分补充了LSB桌面模块的通用部分，其中包含体系结构之间不同的接口。 这部分应与LSB桌面的通用部分结合使用。每当通用部分的某个部分被体系结构特定信息补充时，通用部分会包含对体系结构特定部分的引用。这部分还可能包含未在通用部分中引用的其他信息。 除非另有明确说明，否则在LSB桌面模块的这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。 [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 S390X 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.
