Playsound() plays only a part of the song

[poppy]

I tried to play a wav file with function Playsound() but it played only the first seconds of the song.I would like to play whole the song.What might de be wrong?Here is my code in case someone can help.

/*
This uses the high level WAVE API PlaySound() to play a WAVE file in memory. I simply
open the WAVE file called "nagelas.wav" (ie, in order for this example to
work, you should make sure that you have such a WAVE file on your system). allocate
some memory to completely load the entire file image into memory, and then use that
for PlaySound().
