MACRO Problem

I have defined a macro and have encountered a problem using it. Below is the macro I have defined.

#define BULLET PlaySound("bullet.wav",NULL,SND_FILENAME|SND_ASYNC)

I then try to use it and is successful.

void main()
{
...
    BULLET; // run the macro
...
}

The above works and I heard the sound of one bullet.
However, when I tried to run the macro twice consecutively, it is unsuccessful.

void main()
{
...
    BULLET; // run macro
    BULLET; // another time
...
}

I expect to hear two bullets sound but I only hear one bullet sound.

Why?

This has nothing to do with macros, the problem occurs if you do

PlaySound("bullet.wav",NULL,SND_FILENAME|SND_ASYNC);
PlaySound("bullet.wav",NULL,SND_FILENAME|SND_ASYNC);

right?

the problem is that you try to start 2nd sound before the first one has finsihed.  Don't play asynchronously or place a wait between the two attempts to play.
