ZCOM C I/F Library Routines

ZLTMG (3X)

Chapter 4 243

ZLTMG (3X)

NAME zltmg – Move a logical terminal between groups

SYNOPSIS

#include <zcom/zcomsys.h>

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

int32 zltmg (zap, nap)

zaddr_type *zap;

zaddr_type *nap;

DESCRIPTION Routine zltmg moves the logical terminal associated with a terminal

ZLU to a new group of logical terminals designated by another terminal

ZLU. The first terminal must not be the only terminal linked in its

existing group.

After a successful move, the moved terminal will be a member of the new

group, and its MUX, PORT, and physical terminal linkage are modified

to match the new group.

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).

Threads

Considerations

This routine may be called from a multi-threaded application using the

POSIX (1003.1c) kernel threads API package. This routine has the

following characteristics when called by a multi-threaded application:

cancellation point Thread cancellation can occur when a thread

calls this routine.

async-cancel unsafe The calling thread’s cancelability type must be

PTHREAD_CANCEL_DEFERRED if

cancellation is enabled.

async-signal unsafe It cannot be called from a signal handler.

fork unsafe It cannot be called by a child process after

fork(2) but before exec(2).
