NAME

       ldi_strategy - Device strategy request

SYNOPSIS

       #include <sys/sunldi.h>

       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.

       This function may be called from user or kernel context.
