#include <allegro.h>

int get_sound_input_cap_parm(int rate, int bits, int stereo);

Checks whether the specified recording frequency, number of bits, and  mono/stereo mode are supported (and how) by the current audio driver.

The function returns one of the following possible values:

   0  = It is impossible to record in this format.
   1  = Recording is possible, but audio output
        will be suspended.
   2  = Recording is possible at the same time as
        playing other sounds (full duplex sound card).
   -n = Sampling rate not supported, but rate 'n'
        would work instead.
