.SH 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.

.SH NAME

posix_spawn_file_actions_destroy,

posix_spawn_file_actions_init

\(em destroy and initialize spawn file actions object

(\fBADVANCED REALTIME\fP)

.SH SYNOPSIS

.LP

.nf

#include <spawn.h>

.P

int posix_spawn_file_actions_destroy(posix_spawn_file_actions_t

    *\fIfile_actions\fP);

int posix_spawn_file_actions_init(posix_spawn_file_actions_t

    *\fIfile_actions\fP);

.fi

.SH DESCRIPTION

The

\fIposix_spawn_file_actions_destroy\fR()

function shall destroy the object referenced by

.IR file_actions ;

the object becomes, in effect, uninitialized. An implementation may

cause

\fIposix_spawn_file_actions_destroy\fR()

to set the object referenced by

.IR file_actions

to an invalid value. A destroyed spawn file actions object can be

reinitialized using

\fIposix_spawn_file_actions_init\fR();

the results of otherwise referencing the object after it has been

destroyed are undefined.

.P

The

\fIposix_spawn_file_actions_init\fR()

function shall initialize the object referenced by

.IR file_actions

to contain no file actions for

\fIposix_spawn\fR()

or

\fIposix_spawnp\fR()

to perform.

.P

A spawn file actions object is as defined in

.IR "\fIposix_spawn_file_actions_addclose\fR\^(\|)".

.P

The effect of initializing an already initialized spawn file actions

object is undefined.

.SH "RETURN VALUE"

Upon successful completion, these functions shall return zero;

otherwise, an error number shall be returned to indicate the error.

.SH ERRORS

The

\fIposix_spawn_file_actions_init\fR()

function shall fail if:

.TP

.BR ENOMEM

Insufficient memory exists to initialize the spawn file actions object.

.P

The

\fIposix_spawn_file_actions_destroy\fR()

function may fail if:

.TP

.BR EINVAL

The value specified by

.IR file_actions

is invalid.

.LP

.IR "The following sections are informative."

.SH EXAMPLES

None.

.SH "APPLICATION USAGE"

These functions are part of the Spawn option and need not be

provided on all implementations.

.SH RATIONALE

Refer to the RATIONALE section in

.IR "\fIposix_spawn_file_actions_addclose\fR\^(\|)".

.SH "FUTURE DIRECTIONS"

None.

.SH "SEE ALSO"
