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_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.
