NAME
       ldi_ident_from_dev, ldi_ident_from_stream, ldi_ident_from_dip, ldi_ident_release - ldi cookie management

SYNOPSIS
       #include <sys/sunldi.h>

       int ldi_ident_from_dip(dev_info_t *dip, ldi_ident_t *lip);

       int ldi_ident_from_dev(dev_t dev, ldi_ident_t  *lip);

       void ldi_ident_from_stream(struct queue	*sq, ldi_ident_t  *lip);

       void ldi_ident_release(ldi_ident_t li);

PARAMETERS
       li      ldi identifier.

       lip     ldi identifier pointer.

       dip     Pointer to device info node

       dev     Device number

       sq      Pointer to a stream queue

DESCRIPTION
       The  ldi_ident_from_dev()  function allocates and  returns an ldi identifier  that  is  associated with the device number specified by dev.
       The new ldi identifier is returned via the ldi identifier pointer parameter lip.

       The ldi_ident_from_dip() function allocates and	returns an ldi identifier that is associated with the device info node	    pointed to	by
       dip.  The new ldi identifier is	returned via the ldi identifier pointer parameter lip.

       The  ldi_ident_from_stream()  function allocates and returns an ldi identifier that is associated with the stream pointed to by queue.  The
       new ldi identifier is returned via the ldi identifier pointer parameter lip.

       The ldi_ident_release() function releases an identifier that was allocated via one of the ldi_ident_from()* functions.

RETURN VALUES
       The ldi_ident_from_dev(), ldi_ident_from_dip(), and ldi_ident_from_stream() functions return 0 upon success.

       All of these functions return EINVAL for invalid input parameters.

CONTEXT
       These functions can be called from user or kernel context.
