posix_spawn_file_actions_adddup2(3c)

Standard C Library Functions
                                          posix_spawn_file_actions_adddup2(3C)



NAME
       posix_spawn_file_actions_adddup2  -  add  dup2  action  to  spawn  file
       actions object

SYNOPSIS
       #include <spawn.h>

       int posix_spawn_file_actions_adddup2(
            posix_spawn_file_actions_t *file_actions, int fildes,
            int newfildes);

DESCRIPTION
       The posix_spawn_file_actions_adddup2() function adds a dup2(3C)  action
       to  the object referenced by file_actions that causes the file descrip‐
       tor fildes to be duplicated as newfildes (as if dup2(fildes, newfildes)
       had  been called) when a new process is spawned using this file actions
       object.


       If fildes and newfildes are equal, then the action  shall  ensure  that
       the  FD_CLOEXEC and FD_CLOFORK flags of fildes are cleared (even though
       dup2() would leave them unchanged).


       A    spawn    file    actions    object    is     as     defined     in
       posix_spawn_file_actions_addclose(3C).

RETURN VALUES
       Upon   successful  completion,  the  posix_spawn_file_actions_adddup2()
       function returns 0. Otherwise, an error number is be returned to  indi‐
       cate the error.

ERRORS
       The posix_spawn_file_actions_adddup2() function will fail if:

       EBADF     The  value  specified  by  fildes or newfildes is negative or
                 greater than or equal to {OPEN_MAX}.


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



       The posix_spawn_file_actions_adddup2() function may fail if:

       EINVAL    The value specified by file_actions is invalid.



       It  is  not  considered  an  error  for  the  fildes argument passed to
       posix_spawn_file_actions_adddup2() to specify  a  file  descriptor  for
       which the specified operation could not be performed at the time of the
       call. Any such error will be detected when the associated file  actions
       object is later used during a posix_spawn(3C) or posix_spawnp(3C) oper‐
       ation.
