Use buffer manipulation routines to work with areas of memory on a byte-by-byte basis.
For detailed reference information about the CRT functions, see Alphabetical Function Reference (CRT).
| Routine | Use |
|---|---|
_memccpy |
Copy characters from one buffer to another until given character or given number of characters has been copied |
memchr, wmemchr |
Return pointer to first occurrence, within specified number of characters, of given character in buffer |
memcmp, wmemcmp |
Compare specified number of characters from two buffers |
memcpy, wmemcpy |
Copy specified number of characters from one buffer to another. These functions have been deprecated because a more secure version, memcpy_s, exists. |
memcpy_s |
Copies bytes between buffers. Security-enhanced version of deprecated function memcpy. |
_memicmp |
Compare specified number of characters from two buffers without regard to case |
memmove |
Copy specified number of characters from one buffer to another. This functions has been deprecated because a more secure version, memmove_s, exists. |
memmove_s |
Moves one buffer to another. Security-enhanced version of deprecated function memmove. |
memset, wmemset |
Use given character to initialize specified number of bytes in the buffer |
_swab |
Swap bytes of data and store them at specified location |
When the source and target areas overlap, only memmove is guaranteed to copy the full source properly.
