ZCOM C I/F Library Routines

ZMAPR (3X)

Chapter 4 265

PAR AMETER S

NOTES On a successful return from zmapr, accessing the source ZLU is actually

directed to the destination ZLU. If the source ZLU was a program ZLU,

all messages that were queued on it will be flushed (i.e., returned to the

free queue). If it was a terminal ZLU, the linkage to the terminal is lost.

Usually, this is not desirable because the previously associated terminal

is unusable.

RETURN VALUE Routine zmapr returns 0 if successful. Otherwise, a non-zero error 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;

zaddr_type maddr;

if (ierr = zmapr (&zaddr, &maddr)) {

/* error return code */

}

else {

/* good return code */

}

FILES

mzap ZCOM address to be mapped onto.

/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).
