ZCOM C I/F Library Routines

ZLTQUEUE (3X)

zltqueue – Logical data queue allocation

#include <zcom/zcomsys.h>

#include <zcom/zcomcall.h> /* if compliled with ANSI C (recommended) */

int32 zltqueue (appln, label, queuep)

uint32 appln;

char *label;

uint32 *queuep;

Routine zltqueue requests a data queue in the logical terminal tables for

terminals of a specific application number. There is currently a

maximum of 4 queues. Each queue is identified by the terminal

application group and a user-defined label. The returned queue number

(on successful completion) could then be used in subsequent data storing

and retrieval calls (lt qdput and ltqdget).

The libraries libzcom_c.a and libpthread.a must be linked into thecalling

program by giving the options “-lzcom_c -lpthread” to cc(1) or ld(1).
