In addition to the other replies (pointer vs. array), the return value
should be checked to avoid truncation. You don't want errors like this:
$ cat > foo.c <<'EOD'
#include <stdio.h>
#include <string.h>
int main(int argc, char *argv[]) {
char s[25] = "Message: ";
argc--;
argv++;
while (argc--) {
strlcat(s, *argv++, sizeof(s));
}
puts(s);
return 0;
}
EOD
$ cc -o foo foo.c
$ ./foo "I like your bumerang collection."
Message: I like your bum
