ZCOM C I/F Library Routines
ZINIT (3X)
4. In a multi-threaded application, if this routine is called the second
time by a thread while some ZCOM A PIs a re in-progress in the other
threads, the access to the ZCOM system will be re-initialized. The
in-progress APIs will detect this and ‘retry’ internally.This is handled
automatically and is transparent to the application.
Routine zinit returns 0 if successful. Otherwise, a non-zero error code is
returned. See / opt/acc/include/zcom/zcomsys.h for the lis t of ZCOM
error codes and their meanings.
#include <zcom/zcomsys.h>
#include <zcom/zcomcall.h>
int32 ierr;
zsinfo_type sip;
if (ierr = zinit (&sip)) {
/* error return code */
}
else {
/* good return code */
}
zopen(3X), zrntimer(3X).
/opt/acc/include/zcom/zcomsys.h ZCOM subsystem general include file,
containing data types, data structures,
constants, error codes, masks, etc. Note that
this must be the first include file before any
other ZCOM include files.
/opt/acc/include/zcom/zcomcall.h ZCOM routine function prototypes
(requires ANSI C compilation).
