memcmp, wmemcmp |
Compare specified number of characters from two buffers |
memcpy, wmemcpy, memcpy_s, wmemcpy_s |
Copy specified number of characters from one buffer to another |
_memicmp, _memicmp_l |
Compare specified number of characters from two buffers without regard to case |
memmove, wmemmove,memmove_s, wmemmove_s |
Copy specified number of characters from one buffer to another |
memset, wmemset |
