Hi.

I would like to know if the following code can cause problems
if there's a swap on the drive.

void read_chunk()
{
...
code
fread(sound_fp,.....);
}


static void SB_interrupt_handler()
{

code
...
read_chunk();       /* <------------- In this  function I call fread*/
...
}


My question: if I lock the read_chunk function, is this code safe?
Does it locks automatically the "fread" in the read_chunk function?

Thank you.
