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 , 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 , 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 |
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.
