#### Description [src]

A wrapper around `g_spawn_async_with_pipes_and_fds()` with async-signal-safe implementation of `GSpawnChildSetupFunc` to launch a child program asynchronously resetting the rlimit nofile on child setup.

#### Parameters

`working_directory`

  Type: `const char*`

  Child’s current working directory, or `NULL` to inherit parent’s, in the GLib file name encoding.

  The argument can be `NULL`.
  The data is owned by the caller of the function.
  The value is a platform-native string, using the preferred OS encoding on Unix and UTF-8 on Windows.

`argv`

  Type: An array of `char*`

  Child’s argument vector, in the GLib file name encoding; it must be non-empty and `NULL`-terminated.

  The array must be `NULL`-terminated.
  The data is owned by the caller of the function.
  Each element is a NUL terminated UTF-8 string.

`envp`

  Type: An array of `char*`

      child's environment, or `NULL` to inherit parent's, in the GLib file
      name encoding.

  The argument can be `NULL`.
  The array must be `NULL`-terminated.
  The data is owned by the caller of the function.
  Each element is a NUL terminated UTF-8 string.

`flags`

  Type: `GSpawnFlags`

  Flags from `GSpawnFlags`.

`stdin_fd`

  Type: `int`

  File descriptor to use for child’s stdin, or `-1`.

`stdout_fd`

  Type: `int`

  File descriptor to use for child’s stdout, or `-1`.

`stderr_fd`

  Type: `int`

  File descriptor to use for child’s stderr, or `-1`.

`source_fds`

  Type: An array of `int`

  Array of FDs from the parent process to make available in the child process.

  The argument can be `NULL`.
  The length of the array is specified in the `n_fds` argument.
  The data is owned by the caller of the function.

`target_fds`

  Type: An array of `int`

  Array of FDs to remap `source_fds` to in the child process.

  The argument can be `NULL`.
  The length of the array is specified in the `n_fds` argument.
  The data is owned by the caller of the function.

`n_fds`

  Type: `size_t`

  Number of FDs in `source_fds` and `target_fds`.

`stdin_pipe_out`

  Type: `int*`

  Return location for file descriptor to write to child’s stdin, or `NULL`.

  The argument will be set by the function.
  The argument can be `NULL`.

`stdout_pipe_out`

  Type: `int*`

  Return location for file descriptor to read child’s stdout, or `NULL`.

  The argument will be set by the function.
  The argument can be `NULL`.

`stderr_pipe_out`

  Type: `int*`

  Return location for file descriptor to read child’s stderr, or `NULL`.

  The argument will be set by the function.
  The argument can be `NULL`.

`error`

  Type: `GError **`

  The return location for a recoverable error.

  The argument can be `NULL`.
  If the return location is not `NULL`, then you must initialize it to a `NULL` `GError*`.
  The argument will be left initialized to `NULL` by the function if there are no errors.
  In case of error, the argument will be set to a newly allocated `GError`; the caller will take ownership of the data, and be responsible for freeing it.

#### Return value

Type: `GPid`

The PID of the child on success, 0 if error is set.
