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.
