I want to write a WINS32 API program to detect a sound input from the sound card(I used SB AWE 32)and output the detection to the printer port/serial port. For the serial port, I already figured out how to output the signal by using Assembly Language. However, I don't know how to link my assembly program to the C program that I used for write the API program. 1) Please explain in detail of how API program works and give a pseudo code for this API program that use for sound detection.2) Please provide me some ideas how to link Assembly program to C program.3)Please suggest me where can I get the info about API programming. Give me some titles of the books or authors who are expert in this field.It will be appriciated if you guys can answer me A.S.A.P. Thanks.
