* Name: mempcpy
|
|
*
|
|
* Description:
|
|
* Like memcpy(), but returns address of byte after the last copied byte
|
|
* in dest. This allows constructing data piecewise by copying its parts
|
|
* into consecutive memory locations.
|
|
*
|
|
* This function is not in POSIX.
|
|
*
|
|
* Input Parameters:
|
|
* src - Source location from which to copy.
|
|
* dest - Destination location into which to copy.
|
|
* n - Size of data to be copied, in bytes.
|
|
*
|
|
* Returned Value:
|
|
* A pointer to the byte in dest which immediately follows the last copied
|
|
* byte.
