z/OS UNIX APIs
The following APIs are provided by the z/OS® UNIX element of z/OS and are supported
by the TCP/IP stack in z/OS Communications Server:
- z/OS UNIX sockets
- A set of C language functions
provides support for the z/OS UNIX sockets, which are used
in the z/OS UNIX environment. Programmers use this API to
create applications that conform to the POSIX or XPG4 standard (a UNIX specification). Applications
built with z/OS UNIX sockets can be ported to and from platforms
that support these standards.
The z/OS UNIX sockets support AF_INET and AF_INET6.
- z/OS UNIX assembler callable services
- z/OS UNIX assembler callable services is a generalized
call-based, high-level language interface to z/OS UNIX sockets programming. The functions implemented in this call interface
resemble the z/OS UNIX C sockets implementation, with some extensions
similar to the sockets extended macro interface.
The z/OS UNIX assembler callable services support AF_INET and AF_INET6.
For complete documentation of z/OS UNIX sockets, see z/OS XL C/C++ Runtime Library Reference. For information about z/OS UNIX callable services, see z/OS UNIX System Services Programming: Assembler Callable Services Reference.
