NAME	zltstore – Logical data storage allocation

SYNOPSIS#include <zcom/zcomsys.h>

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

int32 zltstore (appln, label, size, offsetp

uint32 appln;

char *label; uint32 size; int32 *offsetp;

DESCRIPTION Routine zltstore requests a data area in the logical terminal table extension for terminals of a specific application number. Each data area is identified by the terminal application group and a user defined label. The returned offset (on successful completion) could then be used in subsequent data storing and retrieval calls (zltup). For data update and retrieval, using data storage is relatively more efficient than using a data queue. However, due to the limited usable area in the terminal tables, a data queue should be used for large amounts of data. See under zltqueue for how to allocate a data queue.

The libraries libzcom_c.a and libpthread.a must be linked into the calling program by giving the options “-lzcom_c -lpthread” to cc(1) or ld(1).
