memcat()

[chaitanya22]

Like memcpy(), is there any method for appending the array i,e memcat()....how could i use it???

There isn't a memcat() function that corresponds to the strcat() function. If you think about it, a 'memcat' function doesn't make sense. strcat() does string concatenation. A string is a sequence of bytes, terminated by a zero byte. The mem* functions operate on memory, which is a sequence of bytes, but not terminated. Instead, the mem*() functions require that you specify a size for the region of memory you are copying. Given that explanation, memcpy() will do 'memory concatenation' for you:

memcpy(destination + destination_length,source,source_length);
destination_length += source_length;

In this case, you are 'concatenating' a source buffer that is source_length bytes long to the end of a destination buffer that is, prior to the concatenation, destination_length bytes long.
