POSIX_SPAWNATTR_GETPGROUP(3P)IX Programmer's ManualX_SPAWNATTR_GETPGROUP(3P)

PROLOG         top

       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         top

       posix_spawnattr_getpgroup, posix_spawnattr_setpgroup — get and set
       the spawn-pgroup attribute of a spawn attributes object (ADVANCED
       REALTIME)

SYNOPSIS         top

       #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         top

       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         top

       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         top

       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         top

       None.

APPLICATION USAGE         top

       These functions are part of the Spawn option and need not be provided
       on all implementations.

RATIONALE         top

       None.

FUTURE DIRECTIONS         top

       None.
