I'm trying to figure out the best way to write a wrapper around memcpy() which can call fprintf() without winding up getting into a recursive loop. The problem is that fprintf() will call memcpy() and around and around we go. I can use a global variable to prevent this, but that usage isn't thread safe. I can make it thread safe by using pthread keys, but then i have to link in libc_r, and for non-pthreaded programs i don't want to do that. Anyone have any suggestions? Right now I'm almost thinking that I just need to directly patch libc and libc_r. It might be an ugly patch though, and I'd rather not have this patch mandate recompiling all of libc.
