Solved unknown type name 'fd_set'

[balanga]

Can anyone suggest what is causing the error unknown type name 'fd_set' ?

This doesn't occur in FreeBSD, but I'm just wondering where it gets resolved in FreeBSD.

Some context would be nice. So I'm just guessing here, FD_SET(2).

                n = read(fd, buf, len);

                        goto out;

                buf = (char *)buf + n;
                len -= n;

        rc = 0;
out:
        return rc;

Missing

#include <sys/select.h>

perhaps?
