/* DosBeep generates sound from the speaker. */

#define INCL_DOSPROCESS
#include 
#include 

#define MINFREQ   0x0025
#define MAXFREQ   0x7fff
 
int main()
{
  ULONG   ulFrequency;
  ULONG   ulDuration    = 1;

  for(ulFrequency = MINFREQ; ulFrequency < MAXFREQ; ulFrequency+=0x0001) {
    DosBeep(ulFrequency, ulDuration);
    printf("\rulFrequency=0x%04x", ulFrequency);
  }
  return 0;
}
