Make sound with C++

[quantum]

Anyone knows how to produce sound at pc speaker using C++?
It should be fairly common but I cannot seem to find how to do it. Turbo C / Visual C.

For a starter I need some direction or code as to how produce a sound. Any sound with C.

I did little research about making sound in PC speaker with C. And found a sample code. Anyone interested can give this a try.

EXTERN void DoSound( unsigned int , unsigned int ); #if defined(USE_WIN32) void DoSound( unsigned int freq, unsigned int time ) { Beep( freq, time ); return; } #elif defined(USE_DOS) #if defined(__DJGPP__) #undef nosound void nosound(void) { sound(0); return; } #define SLEEP(t) delay(t/2) void DoSound(unsigned int freq, unsigned int time) { sound(freq); SLEEP(time); nosound(); return; } #elif defined(HAVE_SOUND) void DoSound(unsigned int freq, unsigned int time) { sound(freq); sleep(time); nosound(); return; } #else #ifndef LOBYTE #define LOBYTE(w) ((BYTE) (w)) #endif #ifndef HIBYTE #define HIBYTE(w) ((BYTE) (((USHORT) (w) >> 8) & 0xFF)) #endif EXTERN void HWSound( unsigned ); EXTERN void HWNoSound( void ); EXTERN void HWDelay( unsigned ); void HWSound(unsigned int freq) { USHORT counter = 1193280 / freq; /* cycle counter */ outp(0x43, 0xB6); /* prepare timer */ outp(0x42, LOBYTE(counter)); /* send low byte */ outp(0x42, HIBYTE(counter)); /* send high byte */ outp(0x61, inp(0x61) | 0x03); /* turn speaker ON */ return; } void HWNoSound(void) { outp(0x61, inp(0x61) & 0xFC); /* turn speaker OFF */ return; } void HWDelay(unsigned int cc) { time_t delay; delay = clock() + cc; while (delay > clock()); return; } void DoSound(unsigned int freq, unsigned int time) { HWSound(freq); HWDelay(time*1000); HWNoSound(); return; } #endif #else #include <asm/io.h> #include <signal.h> #include <stdio.h> #define outp outb #define inp inb #ifndef LOBYTE #define LOBYTE(w) ((BYTE) (w)) #endif #ifndef HIBYTE #define HIBYTE(w) ((BYTE) (((USHORT) (w) >> 8) & 0xFF)) #endif EXTERN void HWSound( unsigned ); EXTERN void HWNoSound( void ); void HWSound(unsigned int freq) { USHORT counter = 1193280 / freq; /* cycle counter */ outp(0x43, 0xB6); /* prepare timer */ outp(0x42, LOBYTE(counter)); /* send low byte */ outp(0x42, HIBYTE(counter)); /* send high byte */ outp(0x61, inp(0x61) | 0x03); /* turn speaker ON */ return; } void HWNoSound(void) { outp(0x61, inp(0x61) & 0xFC); /* turn speaker OFF */ return; } void DoSound(unsigned int freq, unsigned int time) { HWSound(freq); usleep(time*1000); HWNoSound(); return; } #endif

If anyone else has any more reference or functions or sample codes on this sound issue with C, please reply.

Thanks.
