Copies count
character from character string pointed to by src
to character string pointed to by dest
.
Performs correctly even if the copied character ranges overlap, i.e. src
is in [dest
, dest + count
).
Parameters
dest | - | pointer to a character string to copy to |
src | - | pointer to a character string to copy from |
count | - | the number of characters to copy |
Return value
dest
Exceptions
(none)
Complexity
Linear.
