ZCOM C I/F Library Routines

zport (3X)

RETURN VALUE Routine zport 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.

When zport returns a zero error code, the return status stat indicates the completion status: zero means successful, while non-zero values indicate the reason for the problem. Note that status code 4, 5, 6, and 7 implies the associated port will now be inoperative. Another zport configuration request must be done to recover it.

EXAMPLE		This example puts an E1/T1 port into “loopback” (tristate) mode.
#include		<zcom/zcomsys.h>
#include		<zcom/zcomcall.h>
int32		ierr;
uint32		iftno;
uint32		portno;
uint32		rcode;
uint32		action;
zpconf_type		cnfg;
int32		stat;
iftno	= 1;	/* ACC MUX number 1 in TTGEN configuration file. */
portno = 2;		/* Port #2 */
rcode	= 2;	/* We are providing the configuration in “cnfg”. */

action = ZCOM_ZMUXPORT_PORT; /* Set only the port mode (Pmode, Pmode2) */ cnfg.e1t1_bits.pmode = 0x8;

if (ierr = \fBzport\fR (iftno, portno, rcode, action, cnfg, &stat)) { /* error return code */ } else if (stat)

{

/* error return code */ } else { /* good return code */

}

FILES	/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).
