+.Nm posix_spawn_file_actions_addchdir ,

+.Ft int
+.Fn posix_spawn_file_actions_addfchdir "posix_spawn_file_actions_t * file_actions" "int fildes"
+.Sh DESCRIPTION
+The
+.Fn posix_spawn_file_actions_addchdir
+function shall add a chdir action to the object referenced by
+.Fa file_actions
+that shall cause the working directory to be set to
+.Fa path
+(as if
+.Bd -literal -offset indent
+chdir(path)
+.Ed
+.Pp
+had been called) when a new process is spawned usign this file actions
+object.
+A relative
+.Fa path
+shall be interpreted in relation to the working directory determined by any
+prior actions.
+The string pointed to by
+.Fa path
+shall be copied by the
+.Fn posix_spawn_file_actions_addchdir
+function.
+.Pp
+The
+.Fn posix_spawn_file_actions_addfchdir
+function shall add a fchdir action to the object reference by
+.Fa file_actions
+that shall cause the working directory to be set to
+.Fa fildes
+(as if
+.Bd -literal -offset indent
+fchdir(fildes)
+.Ed
+.Pp
+had been called) when a new process is spawned using this file actions object.
+.\" The last paragraph of APPLICATION USAGE
+.Pp
+File actions are performed in the new process created by
+.Fn posix_spawn
+or
+.Fn posix_spawnp
+in the same order that they were added to the file actions object.
+Thus the execution of an "open" action that was created by a call to
+.Fn posix_spawn_file_actions_addopen
+that specifies a relative path will be affected by the execution of a
+chdir or fchdir action that was created by a previous call to
+.Fn posix_spawn_file_actions_addchdir
+or
+.Fn posix_spawn_file_actions_addfchdir
+\&. Likewise, a relaive path passed to
+.Fn posix_spawn
+will be affected by the last chdir or fchdir action in the file action list.
+.Sh RETURN VALUES
+Upon successful completion, these function return zero;
+otherwise, an error number shall be returned to indicate the error.
+.Sh ERRORS
+The
+.Fn posix_spawn_file_actions_addfchdir
+function shall fail if:
+.Bl -tag -width Er
+.It Bq Er EBADF
+The value specified by
+.Fa fildes
+is negative.
+.El
+.Pp
+These functions shall fail if:
+.Bl -tag -width Er
+.It Bq Er ENOMEM
+Insufficient memory exists to add the spawn file actions object.
+.El
+.Pp
+These functions may fail if:
+.Bl -tag -width Er
+.It Bq Er EINVAL
+The value specified by
+.Fa file_actions
+is invalid.
+.El
+.Pp
+It shall not be considered an error for the
+.Fa path
+or
+.Fa fildes
+argument passed to these functions to specify a pathanme or 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
+.Fn posix_spawn
+or
+.Fn posix_spawnp
+operation.
