PROLOG
This manual page is part of the POSIX Programmer's Manual. The
Linux implementation of this interface may differ (consult the
corresponding Linux manual page for details of Linux behavior),
or the interface may not be implemented on Linux.
NAME
posix_spawnattr_getpgroup, posix_spawnattr_setpgroup — get and
set the spawn-pgroup attribute of a spawn attributes object
(ADVANCED REALTIME)
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 shall obtain the value
of the spawn-pgroup attribute from the attributes object
referenced by attr.
The posix_spawnattr_setpgroup() function shall set 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 shall be zero.
RETURN VALUE
Upon successful completion, posix_spawnattr_getpgroup() shall
return zero and store the value of the spawn-pgroup attribute of
attr into the object referenced by the pgroup parameter;
otherwise, an error number shall be returned to indicate the
error.
Upon successful completion, posix_spawnattr_setpgroup() shall
return zero; otherwise, an error number shall be 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.
The following sections are informative.
EXAMPLES
None.
APPLICATION USAGE
These functions are part of the Spawn option and need not be
provided on all implementations.
RATIONALE
None.
FUTURE DIRECTIONS
None.
