So you have unsigned char *bytes;
and then datasize = (unsigned int)bytes; which sets datasize to the address of bytes cast to an unsigned integer which has nothing to do with the data in bytes at all and in some cases just truncates the address (OSX for instance) datasize = *((unsigned int*)bytes); is a bit closer to what you might want but is endian-unaware.
