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
