From 766c5bc6ae24fe2ec03ada80905ccfb1b18afc26 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Tue, 11 Mar 2014 22:58:07 +0100 Subject: lib: extract ioctl_wrappers.c I want to group the ioctl wrappers and related functions into their own documentation section. Apparently gtkdoc refuses to obey this wish without a corespdonding header. So appease it. Also gtkdoc seems to struggle with rebuilding a bit ...
