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