PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may differ (con-
       sult the corresponding Linux manual page for details of Linux behavior), or the  interface  may  not  be  implemented  on
       Linux.

NAME
       posix_spawnattr_getflags,  posix_spawnattr_setflags  - get and set the spawn-flags attribute of a spawn attributes object
       (ADVANCED REALTIME)

SYNOPSIS
       #include <spawn.h>

       int posix_spawnattr_getflags(const posix_spawnattr_t *restrict attr,
              short *restrict flags);
       int posix_spawnattr_setflags(posix_spawnattr_t *attr, short flags);


DESCRIPTION
       The posix_spawnattr_getflags() function shall obtain the value of the spawn-flags attribute from  the  attributes  object
       referenced by attr.

       The  posix_spawnattr_setflags()  function  shall set the spawn-flags attribute in an initialized attributes object refer-
       enced by attr.

       The spawn-flags attribute is used to indicate which process attributes are to be changed in the new  process  image  when
       invoking posix_spawn() or posix_spawnp(). It is the bitwise-inclusive OR of zero or more of the following flags:

       POSIX_SPAWN_RESETIDS
       POSIX_SPAWN_SETPGROUP
       POSIX_SPAWN_SETSIGDEF
       POSIX_SPAWN_SETSIGMASK

       POSIX_SPAWN_SETSCHEDPARAM
       POSIX_SPAWN_SETSCHEDULER


       These flags are defined in <spawn.h>. The default value of this attribute shall be as if no flags were set.

RETURN VALUE
       Upon successful completion, posix_spawnattr_getflags() shall return zero and store the value of the spawn-flags attribute
       of attr into the object referenced by the flags parameter; otherwise, an error number shall be returned to  indicate  the
       error.

       Upon successful completion, posix_spawnattr_setflags() 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_setflags() function may fail if:

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


       The following sections are informative.

APPLICATION USAGE

RATIONALE
       None.

FUTURE DIRECTIONS
