Has anyone actually *tried* readlink() on linux? I did.
If the result is too long, it is silently truncated to fit the buffer,
and no error is returned.
main(int argc, char **argv)
{
int i;
char buf[20];
memset (buf, 0, sizeof(buf));
i = readlink (argv[1], buf, 1);
printf ("ret %d `%s'\n", i, buf);
perror ("errno");
}
