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.
