NAME

     VOP_STRATEGY — read or write a file system buffer

SYNOPSIS

     #include <sys/param.h>
     #include <sys/vnode.h>

     int
     VOP_STRATEGY(struct vnode *vp, struct buf *bp);

DESCRIPTION

     The arguments are:

     vp  The vnode that the buffer is for.

     bp  The buffer to be read or written.

     This call either reads or writes data from a file, depending on the value of
     bp->b_io.bio_cmd.

     The call may block.

RETURN VALUES

     Always zero.  Errors should be signalled by setting BIO_ERROR on b_ioflags field in struct
     buf, and setting b_error to the appropriate errno value.
