ldi_get_size, ldi_get_blksize, ldi_get_pblksize - Retrieve device size properties
#include <sys/sunldi.h> int ldi_get_size(ldi_handle_t lh, uint64_t *sizep);
int ldi_get_blksize(ldi_handle_t lh, uint34_t *blksizep);
int ldi_get_pblksize(ldi_handle_t lh, uint32_t *pblksizep);
Layered handle.
Pointer to the caller's unsigned 64-bit integer buffer.
Pointer to the caller's unsigned 32-bit integer buffer
Pointer to the caller's unsigned 32-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).
The ldi_get_blksize() function uses the layered driver handle to return a device's logical block size. Its value is returned within the caller supplied buffer (*blksizep).
The ldi_get_pblksize() function uses the layered driver handle to return a device's physical block size. Its value is returned within the caller supplied buffer (*pblksizep).
A valid layered driver handle must be obtained via the ldi_open_by_name(9F) interface prior to calling ldi_get_size(), ldi_get_blksize(), and ldi_get_pblksize().
The ldi_get_size() function returns the following values:
The device size property has been returned within the caller supplied buffer.
The device size property could not be found or determined.
These functions may be called from user or kernel context.
