This function doesn’t check for any terminating null wide character in the first string called source it always copies exactly n characters to the second string called destination.
wchar_t* wmemcpy( wchar_t* destination, const wchar_t* source, size_t n )
Parameter : The function accepts three mandatory parameters which are described below:
- destination: specifies a pointer where the characters are to be copied .
- source: specifies a pointer where the data are present .
