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.
