PROLOG
       This  manual page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may differ (consult the correspond-
       ing 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 referenced 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.

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.
