memcpy
void memcpy(void &pToBuffer, const void &pFromBuffer, const short nNumbOfBytes) | ||||||||||||
(void) Function copies characters from pFromBuffer to pToBuffer. nBytesToCopy is the number of bytes to copy. Identical to the function found in conventional C 'string.h' library. | ||||||||||||
| ||||||||||||
|
memset
void memset(void &pToBuffer, const short nValue, const short nNumbOfBytes) | ||||||||||||
(void) Sets a block of memory at pToBuffer to the value nValue. nNumbOfBytes is the number of bytes to set. This is a useful function for initializing the value of an array to all zeros. Identical to the function found in conventional C 'string.h' library. | ||||||||||||
| ||||||||||||

memcmp
intrinsic short memcmp(void &pToBuffer, void &pFromBuffer, const short nNumbOfBytes) | ||||||||||||
(void) Compares the first set bytes of the block of memory referenced by "pToBuffer" to the first number of bytes referenced by "pFromBuffer". The function will return zero if they all match or a value different from zero representing which is greater if they do not. | ||||||||||||
| ||||||||||||
|
memmove
void memmove(void &pToBuffer, const void &pFromBuffer, const short nNumbOfBytes) | ||||||||||||
(void) Function copies characters from pFromBuffer to pToBuffer. nBytesToCopy is the number of bytes to copy. Identical to the function found in conventional C 'string.h' library.
The advantage of "memmove" is that the buffers can overlap in memory space - the "memcpy" function they cannot overlap. | ||||||||||||
