What is sounds like you're saying is something like:
const char * str = Hello;
//thread 1
char bufferA[20]:
strncpy(bufferA, str, sizeof(bufferA));
//thread 2
char bufferB[20]:
strncpy(bufferB, str, sizeof(bufferB));
is unsafe and needs a lock?

Hi,
I am trying to implement iTunes-Equalizer kind of functionality to my
mp3 playback.
Can any body direct me how to do this.
I started looking into CoreAudio frameworks.
So far I couldn't get how to set the frequency to the Audio.
Any help.
thanks in Advance
