       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_spawn_file_actions_destroy,  posix_spawn_file_actions_init  — destroy and initialize
       spawn file actions object (ADVANCED REALTIME)

SYNOPSIS

       #include <spawn.h>

       int posix_spawn_file_actions_destroy(posix_spawn_file_actions_t
           *file_actions);
       int posix_spawn_file_actions_init(posix_spawn_file_actions_t
           *file_actions);

DESCRIPTION

       The posix_spawn_file_actions_destroy() function shall destroy  the  object  referenced  by
       file_actions;  the  object  becomes, in effect, uninitialized. An implementation may cause
       posix_spawn_file_actions_destroy() to set the object  referenced  by  file_actions  to  an
       invalid  value.  A  destroyed  spawn  file  actions  object  can  be  reinitialized  using
       posix_spawn_file_actions_init(); the results of otherwise referencing the object after  it
       has been destroyed are undefined.

       The  posix_spawn_file_actions_init()  function  shall  initialize the object referenced by
       file_actions to contain no file actions for posix_spawn() or posix_spawnp() to perform.

       A spawn file actions object is as defined in posix_spawn_file_actions_addclose().

       The effect of initializing an already initialized spawn file actions object is undefined.

RETURN VALUE

       Upon successful completion, these functions shall return zero; otherwise, an error  number
       shall be returned to indicate the error.

ERRORS

       The posix_spawn_file_actions_init() function shall fail if:

       ENOMEM Insufficient memory exists to initialize the spawn file actions object.

       The posix_spawn_file_actions_destroy() function may fail if:

       EINVAL The value specified by file_actions is invalid.

       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

       Refer to the RATIONALE section in posix_spawn_file_actions_addclose().

FUTURE DIRECTIONS

       None.
