bcopy - Copy one area of memory to another
char * bcopy (const char *src, char *dest, int count);
src Where to copy from dest Where to copy to count The size of the area.
Note that this is the same as memcpy, with the arguments reversed. memcpy is the standard, bcopy is a legacy BSD function. You should not use this function to access IO space, use memcpy_toio or memcpy_fromio instead.
