POSIX_SPAWNATTR_GETPGROUP(3C)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_SETPGROUP 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.
