ldi_strategy(9F) Kernel Functions for Drivers ldi_strategy(9F)NAME
ldi_strategy - Device strategy request
SYNOPSIS
#include <sys/sunldi.h>
int ldi_strategy(ldi_handle_t lh, struct buf *bp);
PARAMETERS
lh Layered handle.
bp Pointer to the buf(9S) structure.
DESCRIPTION
The ldi_strategy() function passes a strategy request to the device entry point for the device specified by the layered handle. This opera-
tion is supported for block devices.
RETURN VALUES
The ldi_strategy() function returns 0 if the strategy request has been passed on to the target device. Other possible return values are:
EINVAL Invalid input parameters.
ENOTSUP Operation is not supported for this device.
Once the request has been passed on to the target devices strategy entry point, any further errors will be reported by bioerror(9F) and
biodone(9F). See the strategy(9E) entry point for more information.
CONTEXT
This function may be called from user or kernel context.

Hi
I'd like to know a logic or a strategy to count the number of I/O requests that are being made. I have the PID of the process for which this needed to be done. Does anyone have any clue as to how to do this? This is to be done in Kernel programming in C.
P.S:
