     #include <sys/uio.h>
     #include <sys/bio.h>
     #include <sys/buf.h>

     int
     BUF_TIMELOCK(struct buf *bp, int locktype, char *wmesg, int catch, int timo);

     catch     Priority OR'd into the sleep's priority.

     timo      The timeout for any sleeps encountered during the lock.
