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.

.SH NAME
posix_spawnattr_getflags,
posix_spawnattr_setflags
\(em get and set the spawn-flags attribute of a spawn attributes object
(\fBADVANCED REALTIME\fP)
.SH SYNOPSIS
.LP
.nf
#include <spawn.h>
.P
int posix_spawnattr_getflags(const posix_spawnattr_t *restrict \fIattr\fP,
    short *restrict \fIflags\fP);
int posix_spawnattr_setflags(posix_spawnattr_t *\fIattr\fP, short \fIflags\fP);
.fi
.SH DESCRIPTION
The
\fIposix_spawnattr_getflags\fR()
function shall obtain the value of the
.IR spawn-flags
attribute from the attributes object referenced by
.IR attr .
.P
The
\fIposix_spawnattr_setflags\fR()
function shall set the
.IR spawn-flags
attribute in an initialized attributes object referenced by
.IR attr .
.P
The
.IR spawn-flags
attribute is used to indicate which process attributes are to be
changed in the new process image when invoking
\fIposix_spawn\fR()
or
\fIposix_spawnp\fR().
It is the bitwise-inclusive OR of zero or more of the following flags:
.P
.nf
POSIX_SPAWN_RESETIDS
POSIX_SPAWN_SETPGROUP
POSIX_SPAWN_SETSIGDEF
POSIX_SPAWN_SETSIGMASK
POSIX_SPAWN_SETSCHEDPARAM
POSIX_SPAWN_SETSCHEDULER
.fi
.P
These flags are defined in
.IR <spawn.h> .
The default value of this attribute shall be as if no flags were set.
.SH "RETURN VALUE"
Upon successful completion,
\fIposix_spawnattr_getflags\fR()
shall return zero and store the value of the
.IR spawn-flags
attribute of
.IR attr
into the object referenced by the
.IR flags
parameter; otherwise, an error number shall be returned to indicate the
error.
.P
Upon successful completion,
\fIposix_spawnattr_setflags\fR()
shall return zero; otherwise, an error number shall be returned to
indicate the error.
.SH ERRORS
These functions may fail if:
.TP
.BR EINVAL
The value specified by
.IR attr
is invalid.
.P
The
\fIposix_spawnattr_setflags\fR()
function may fail if:
.TP
.BR EINVAL
The value of the attribute being set is not valid.
.LP

.SH EXAMPLES
None.
.SH "APPLICATION USAGE"
These functions are part of the Spawn option and need not be
provided on all implementations.
.SH RATIONALE
None.
.SH "FUTURE DIRECTIONS"
None.
