how to stop playing WAV file while using tmrpcm?

I need to play WAV file and also writing a file to SD card; for playing WAV file i use <tmrpcm.h> library, according discussion somewhere in this forum, i need to stop all WAV plays/reading before writing something to SD card because we can’t do that simultaneously.
my question is in <tmrpcm.h> library file. i found some function that i think should stop reading WAV file in SD card.
Code: [Select]

void stopPlayback();
void disable();
void pause();

i dont know what is the literally meaning of all those function and which one i should choose? can anyone explain it to me? Thanks in advance.
