Say my source buffer = 630000 bytes, destination buffer = 630272 bytes
So on fisr iteration of memcopy i would copy the whole 630000bytes of my source buffer into my destination buffer, so at this point destination buffer is left with 272bytes more room, so what I want is to copy the first 272 bytes of source buffer into the remaining destination buffer.
Is there anyway to implement this using memcpy() or memmove() etc functions?? I would really appreciate if anyone can help me out in this.

void strangecopy(char *dest, int destsize, char *source, int sourcesize)
{
    do 
    {
        if (destsize<sourcesize)
        {
            // destination is too small truncate copy
            memcpy(dest,source,destsize);
        } else 
        {
           // destination is larger or equal, fill
           memcpy(dest,source,sourcesize);
        }
        dest+=sourcesize;
        destsize-=sourcesize;
    } while (destsize>sourcesize);
}
