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.
