RETURN VALUE Routine zsend returns 0 if successful. Otherwise, a non-zero error code
is returned. See /opt/acc/include/zcom/zcomsys.h for the list of ZCOM
error codes and their meanings.
If mode ZcMODE_WAIT is used and zsend returns with zero, rstat
contains the return status: 0 means successful, non-zero means there
was a problem with the send. zcomstatus(3X)maybeusedtoretrievea
status message, using request code ZCOM_MRQCODE_WRITE and
rstat.
