使用X11（GTK，GDK）功能从C发送键组合

Question

I need exact equivalent of command (in C code)

system("xdotool key alt+o");

but much more portable (and less overloaded for so simple task). I write for GTK so i prefer some GTK function, but something for GDK or even for X11 also looks to be portable. Thanks.

Here's an example that does what you want:

It's command-line, but it's short and it's pretty easy to understand so turning it into something your code can call should be easy.
