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.

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 in posix_spawn_file_actions_addclose() .

FUTURE DIRECTIONS
