#include
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);
int ldi_ident_from_stream(struct queue *sq, ldi_ident_t *lip);

PARAMETERS
li ldi identifier lip ldi identifier pointer dip pointer to device info node dev device number sq pointer to a stream queueDESCRIPTION
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 in 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 in 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 in the ldiSunOS 5.11 Last change: 26 Mar 2009 1

identifier pointer parameter lip.The ldi_ident_release() function releases an identifier that
was allocated by 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
