get_color_depth - Man Page

#include <allegro.h>

int get_color_depth(void);

Returns the current pixel format. This can be very useful to know in order to write generic functions which select a different code path internally depending on the color depth being used.

Note that the function returns whatever value you may have set previously with set_color_depth(), which can be different from the current color depth of the screen global variable. If you really need to know the color depth of the screen, use bitmap_color_depth().

exrgbhsv(3), set_color_depth(3).
