Hello all,

I'm trying to find where exactly xnu, MacOS X's kernel, is getting access to strcpy and strcat. I can't seem to find either C files anywhere though the kernel makes extensive use of both functions. The only think I can find is in string.h giving the functions extern ... does this mean it is actually using the same C files that the rest of the system uses in development or is there an area (or a psecific file) that houses the strcat/strcpy C files?
