Hi Guys
 
I have found an inccorect man page, 
Using  4.5-RELEASE FreeBSD 4.5-RELEASE #19:

typing man physio
 you get

<snip>
 #include <sys/buf.h>

     int
     physio(dev_t dev, struct uio *uio, int ioflag);

DESCRIPTION
     The physio() is a helper function typically
called from character device
<snip>
.
.
.
<snip>
 A break-down of the arguments follows:

     strategy
             The device strategy routine to call for
each chunk of data to
             initiate device I/O.

     bp      The buffer to use with the strategy
routine.  The buffer flags
             will have B_BUSY, and B_PHYS set when
passed to the strategy rou-
             tine.  If NULL, a buffer is allocated
from a system pool.

     dev     The device number identifying the device
to interact with.

     flags   Direction of transfer; the only valid
settings are B_READ or
             B_WRITE.

     minphys
             A device specific routine called to
determine the maximum trans-
             fer size that the device's strategy
routine can handle.

     uio     The description of the entire transfer as
requested by the user
             process.  Currently, the results of
passing a uio structure with the `uio_segflg' set to
anything other than UIO_USERSPACE, are
             undefined.

RETURN VALUES
<snip>

Thus the paramters the function actually takes (as per
definition in /usr/src/include/buf.h ). Do match the
breakdown of the arguments in the man page.

I hope this is of some use.

Later
David
