POSIX_SPAWNATTR_GETFLAGS(P)	    POSIX Programmer's Manual	      POSIX_SPAWNATTR_GETFLAGS(P)

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 initial-
       ized 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 parame-
       ter; 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  implementa-
       tions.

RATIONALE
       None.

FUTURE DIRECTIONS
       None.
