posix_spawnattr_getpgroup(3C)				   Standard C Library Functions 			     posix_spawnattr_getpgroup(3C)

NAME

       posix_spawnattr_getpgroup, posix_spawnattr_setpgroup - get and set spawn-pgroup attribute of spawn attributes object

SYNOPSIS

       #include <spawn.h>

       int posix_spawnattr_getpgroup(const posix_spawnattr_t *restrict attr,
	    pid_t *restrict pgroup);

       int posix_spawnattr_setpgroup(posix_spawnattr_t *attr, pid_t pgroup);

DESCRIPTION

       The posix_spawnattr_getpgroup() function obtains the value of the spawn-pgroup attribute from the attributes object referenced by attr.

       The posix_spawnattr_setpgroup() function sets the spawn-pgroup attribute in an initialized attributes object referenced by attr.

       The  spawn-pgroup  attribute  represents the process group to be joined by the new process image in a spawn operation (if POSIX_SPAWN_SETP-
       GROUP is set in the spawn-flags attribute). The default value of this attribute is zero.

RETURN VALUES

       Upon successful completion, posix_spawnattr_getpgroup() returns 0 and stores the value of the  spawn-pgroup  attribute  of  attr  into  the
       object referenced by the pgroup parameter. Otherwise, an error number is returned to indicate the error.

       Upon successful completion, posix_spawnattr_setpgroup() returns 0. Otherwise, an error number is returned to indicate the error.

ERRORS

       These functions may fail if:

       EINVAL	 The value specified by attr is invalid.

       The posix_spawnattr_setpgroup() function may fail if:

       EINVAL	 The value of the attribute being set is not valid.
