list_config_sections - Lists the names of all sections available in the current
configuration. Allegro game programming library.
#include <allegro.h>
int list_config_sections(const char ***names);
The names parameter is a pointer to an array of strings. If it points to a NULL
pointer, the list will be allocated, else it will be re-allocated. After the
function returns, it will contain the names of all sections in the current
configuration. Use free_config_entries to free the allocated memory again. See
list_config_entries for more information and an example how to use it.
Returns the number of valid strings in the names array.
