[PATCH 1/4] lib: extract ioctl_wrappers.c

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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 ...
