Preface
*******

This is the User's Guide for the POSIX API support provided in RTEMS.

The functionality described in this document is based on the following standards:

  * POSIX 1003.1b-1993.

  * POSIX 1003.1h/D3.

  * Open Group Single UNIX Specification.

Much of the POSIX API standard is actually implemented in the Cygnus Newlib ANSI C Library.  Please refer to documentation on Newlib for more information on the functionality it supplies.

This manual is still under construction and improvements are welcomed from users.
