I think you meant strcat here too. I'd remember the first length and I
like to add in the extras like this:
size_t l1 = strlen(first);
char *name = malloc(l1 + 1 + strlen(second) + 1);
if (name) {
memcpy(name, first, l1);
name[l1] = '/';
strcpy(name + l1 + 1, second);
}
Also, for some file names, you can use a VLA as I suggested in another
post.
