System Interfaces (XSH)

XSH is part of the Base Specifications, Issue 7. XSH describes a set of system interfaces offered to application programs by systems conformant to this volume of the Single UNIX Specification. Readers are expected to be experienced C language programmers, and to be familiar with the XBD volume.

This volume is structured as follows:

  • Chapter 1 explains the relationship of XSH to other formal standards and describes the format of the reference pages that comprise most of this volume.

  • Chapter 2 contains important concepts, terms, and caveats relating to the rest of XSH. This includes information on the compilation environment, the name space, definitions of error numbers, signal concepts, standard I/O streams, STREAMS, XSI IPC, realtime, threads, sockets, tracing, and data types.

  • Chapter 3 defines the functional interfaces to systems conformant to this volume of the Single UNIX Specification. These are in the form of reference pages and are organized alphabetically.
