ZCOM C I/F Library Routines

ZLTUP (3X)

async-cancel unsafe The calling thread’s cancelability type must be

	PTHREAD_CANCEL_DEFERRED if
	cancellation is enabled.
async-signal unsafe It cannot be called from a signal handler.
fork unsafe	It cannot be called by a child process after fork(2)
	but before exec(2).

PARAMETERS

zap ZCOM address.

ibuf Data buffer.

len Byte length of buffer.

offse Byte offset within the logical terminal table where the data in the

tbuffer should be placed. See NOTES for information on finding the offsets.

NOTES	The offset returned by zltstore may be passed to zltup to update the
	allocated storage area in the extension area. To update the fields in the
	basic table, the offset may be worked out by the ZCOM_OFFSET macro
	(defined in zcomsys.h). For example, to get the offset for the application
	number field ltapno:
	int32	offset;
	zltt_type	ltt, *lttp;
	offset = ZCOM_OFFSET (*lttp, ltapno);		<-- Both will work
	offset = ZCOM_OFFSET (ltt, ltapno);		<-- Both will work
RETURN VALUE	Routine zltup returns 0 if successful. Otherwise, a non-zeroerror code
	is returned. See /opt/acc/include/zcom/zcomsys.h for the list of ZCOM
	error codes and their meanings.
EXAMPLE	#include	<zcom/zcomsys.h>
	#include	<zcom/zcomcall.h>
	int32	ierr;
	zaddr_type	zaddr;
	char	ibuf[size]; /* where size is user-defined; must
	be >= len */
