X Window System routines: What is provided with z/OS UNIX System Services

The z/OS UNIX System Services X Window System support provided with TCP/IP includes the following APIs:

SEZAROE1 and SEZACMTX compiled to run under z/OS UNIX System Services. SEZAROE1 is a combination of the reentrant versions of the X Window System libraries (see z/OS Communications Server: IP Sockets Application Programming Interface Guide and Reference for information about data sets).
.SEZAROE2 (z/OS UNIX System Services Athena Widget set for reentrant modules).
SEZAROE3 (z/OS UNIX System Services Motif Widget set for reentrant modules).
The SEZAROE1, SEZAROE2, and SEZAROE3 library members are:
- Fixed block 80, in object deck format.
- Compiled with the C/370™ RENT compile-time option.
- Used as input for reentrant z/OS UNIX System Services X Window System and socket programs.
- Passed to the C/370 prelinker. Use the prelink utility to combine all input text decks into a single text deck.
