Method
GioSubprocessLaunchertake_fd
Declaration
void
g_subprocess_launcher_take_fd (
GSubprocessLauncher* self,
gint source_fd,
gint target_fd
)
Description
Transfer an arbitrary file descriptor from parent process to the
child. This function takes ownership of the source_fd; it will be closed
in the parent when self is freed.
By default, all file descriptors from the parent will be closed.
This function allows you to create (for example) a custom pipe() or
socketpair() before launching the process, and choose the target
descriptor in the child.
An example use case is GNUPG, which has a command line argument
--passphrase-fd providing a file descriptor number where it expects
the passphrase to be written.
