NAME

       ldi_get_dev, ldi_get_otyp, ldi_get_devid, ldi_get_minor_name - Extract information from a layered handle

SYNOPSIS

       #include <sys/sunldi.h>

       int ldi_get_dev(ldi_handle_t lh, dev_t *devp);

       int ldi_get_otyp(ldi_handle_t lh, int *otyp);

       int ldi_get_devid(ldi_handle_t lh, ddi_devid_t *devid);

       int ldi_get_minor_name(ldi_handle_t lh, char **minor_name);

PARAMETERS

       lh	       Layered handle

       otyp	       Indicates on which interface the driver was opened. Valid settings are:

		       OTYP_BLK        Open device block interface.

		       OTYP_CHR        Open device character interface.

       devp	       Pointer to a device number.

       devid	       Device ID.

       minor_name      Minor device node name.

DESCRIPTION

       The ldi_get_dev() function retrieves the dev_t associated with a layered handle.

       The ldi_get_otyp() retrieves the open flag that was used to open the device associated with the layered handle.

       The  ldi_get_devid()  function retrieves a devid for the device associated with the layered handle. The caller  should use ddi_devid_free()
       to free the devid when done with it.

       The ldi_get_minor_name() function retrieves the name of the  minor  node  opened  for  the  device  associated  with  the  layered  handle.
       ldi_get_minor_name()  allocates a buffer containing the minor node name and returns it via the minor_name parameter.  The caller should use
       kmem_free() to release the buffer when done with it.

RETURN VALUES

       The ldi_get_dev(), ldi_get_otyp(), ldi_get_devid(), and ldi_get_devid() functions return 0 upon success.

       In case of an error, the following values may be returned:

       EINVAL	       Invalid input parameters.

       ENOTSUP	       The operation is not supported for this device.

CONTEXT

       These functions may be called from user or kernel context.
