close

Closes all the file descriptors previously passed to the object with g_subprocess_launcher_take_fd(), g_subprocess_launcher_take_stderr_fd(), etc.

After calling this method, any subsequent calls to g_subprocess_launcher_spawn() or g_subprocess_launcher_spawnv() will return %G_IO_ERROR_CLOSED. This method is idempotent if called more than once.

This function is called automatically when the #GSubprocessLauncher is disposed, but is provided separately so that garbage collected language bindings can call it earlier to guarantee when FDs are closed.
