set_config_file - Sets the configuration file. Allegro game programming library.
#include <allegro.h>
void set_config_file(const char *filename);
Sets the configuration file to be used by all subsequent config functions.
(Allegro will not search for this file in other locations as it does with
allegro.cfg at the time of initialization.)
All pointers returned by previous calls to get_config_string() and
other related functions are invalidated when you call this function! You can
call this function before install_allegro() to change the configuration
file, but after set_uformat() if you want to use a text encoding format
other than the default.
