[C] post your gets()

As we know, gets() is unsafe, fgets() annoyingly retains the '\n', getline() is non-standard, and scanf() always stops at spaces.  Many of us wind up rolling our own.

This one
1. always NUL-terminates
2. is efficient since there are only two tests in the main loop
3. discards everything until the end of the line if truncation occurs.

void
getstr(char *s, size_t siz)
{
        int     c;
        char    *max = s + siz - 1;

        while ((c = getchar()) != '\n' && s < max)
                *s++ = c;
        *s = '\0';
        while (c != '\n')
                c = getchar();
}
