Declaration [src]
void
g_subprocess_launcher_take_stdout_fd (
GSubprocessLauncher* self,
gint fd
)
Description [src]
Sets the file descriptor to use as the stdout for spawned processes.
If fd is -1 then any previously given fd is unset.
Note that the default behaviour is to pass stdout through to the stdout of the parent process.
The passed fd is noted but will not be touched in the current
process. It is therefore necessary that it be kept open by the
caller until the subprocess is spawned. The file descriptor will
also not be explicitly closed on the child side, so it must be marked
O_CLOEXEC if that’s what you want.
You may not set a stdout fd if a stdout file path is already set or if the launcher flags contain any flags directing stdout elsewhere.
This feature is only available on UNIX.
