memcpy

Copies count characters from the source memory area, pointed to by src, and writes this character string to a destination memory area, pointed to by dest.

Syntax:

char *memcpy (dest, src, count)
char *dest, *src;
int count;

where:

dest                      A character pointer that specifies the starting address for the destination memory area, to begin writing characters to.

src                        A character pointer that specifies the starting address for the source memory area, to begin copying characters from.

count                    An integer variable specifying the number of characters (bytes) to be copied, from the source location, to the destination location of memory.

Return Value

Pointer to char       Points to the destination location that is one byte beyond the last byte written to. This allows continuation of the writing process with perfect alignment of bytes for string concatenation of memory blocks.

Rules

None.
