ZCOM C I/F Library Routines

ZLTSTORE (3X)

Routine zltstore returns an already assigned area if the application number and storage label and storage size all match a previously assigned area. Otherwise, an error is returned. This provides a facility to share data areas between different programs and enables program restartability.

If bit ZCOM_ZLTSTORE_NA (0x8000) of the size parameter is set before zltstore is called, then zltstore will only return a previously assigned area. If a matching area of storage is not assigned, this will result in an error return. If this bit of the size parameter is zero, a new storage area will be allocated if it is not already assigned.

RETURN VALUE

Routine zltstore 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;

 

 

uint32

appln;

 

 

char

label[6];

 

 

uint32

size;

 

 

int32

offset;

 

 

if (ierr = zltstore (appln, label, size, &offset)) {

 

 

/* 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
