LDI_GET_SIZE(9F) Kernel Functions for Drivers LDI_GET_SIZE(9F)

ldi_get_size - Retrieve device size

#include <sys/sunldi.h>
int ldi_get_size(ldi_handle_t lh, uint64_t *sizep);

lh
Layered handle.

sizep

Pointer to the caller's unsigned 64-bit integer buffer.

The ldi_get_size() function uses the layered driver handle to calculate and return a device's size. The device size is returned within the caller supplied buffer (*sizep). A valid layered driver handle must be obtained via the ldi_open_by_name(9F) interface prior to calling ldi_get_size().

The ldi_get_size() function returns the following values:

DDI_SUCCESS

The device size has been returned within the caller supplied buffer.

DDI_FAILURE

The device size could not be found or determined.

This function may be called from user or kernel context.
