Buffer Manipulation
Use these routines to work with areas of memory on a byte-by-byte basis.
Buffer-Manipulation Routines
| Routine | Use |
| _memccpy | Copy characters from one buffer to another until given character or given number of characters has been copied |
| memchr | Return pointer to first occurrence, within specified number of characters, of given character in buffer |
| memcmp | Compare specified number of characters from two buffers |
| memcpy | Copy specified number of characters from one buffer to another |
| _memicmp | Compare specified number of characters from two buffers without regard to case |
| memmove | Copy specified number of characters from one buffer to another |
| memset | 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.
