VOP_STRATEGY – read or write a file system buffer

SYNOPSIS DESCRIPTION RETURN VALUES SEE ALSO AUTHORS

#include <sys/param.h>

#include <sys/buf.h>

#include <sys/vnode.h>

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

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_iocmd.

The call may block.

Always zero. Errors should be signalled by setting the BIO_ERROR bit in bp->b_ioflags and setting bp->b_error to the appropriate errno value.
