RETURN VALUE Routine zx25callrej returns a 0 when successful. If there was a ZCOM
error, it returns a negative value. (See
/opt/acc/include/zcom/zcomsys.h for the list of ZCOM error codes and
their meanings.) If zx25callrej, itself, failed, one of the following positive
error codes is returned:
ZxeUNKNOWN_L2_ZLU (02) Unable to find the X.25 link ZLU for
this SVC ZLU.
ZxeREQ_TIMEOUT (04) The remote ZCOM system did not
respond within 30 seconds.
ZxeNOT_A_SVC (05) The ZLU specified is a PVC ZLU. You
must specify an SVC ZLU with this

structure does not contain the same
address that was passed to the
zx25info() routine.
