       dlpi_send - send a data message using DLPI

       cc [ flag... ] file... -ldlpi [ library... ]
       #include <libdlpi.h>

       int dlpi_send(dlpi_handle_t dh, const void *daddrp,
	    size_t daddrlen, const void *msgbuf, size_t msglen,
	    const dlpi_sendinfo_t *sendp);

       The  dlpi_send()	 function attempts to send the contents of msgbuf over
       the DLPI link instance associated with the DLPI handle dh to the desti‐
       nation  address specified by daddrp. The size of msgbuf and  daddrp are
       provided by  the	 msglen	 and  daddrlen	arguments,  respectively.  The
       attempt	will  fail if dh is not in the DL_IDLE DLPI state, the address
       named by daddrp is invalid, daddrlen is larger than  DLPI_PHYSADDR_MAX,
       or msglen is outside the range reported by dlpi_info(3DLPI).

       If the sendp argument is NULL, data is sent using the bound SAP associ‐
       ated with dh (see dlpi_bind(3DLPI)) and with default priority.	Other‐
       wise,  sendp must point to a dlpi_sendinfo_t structure defined in <lib‐
       dlpi.h> as follows:

	 typedef struct {
		 uint_t		 dsi_sap;
		 dl_priority_t	 dsi_prio;
	 } dlpi_sendinfo_t;

       The dsi_sap value indicates the SAP to use  for	the  message  and  the
       dsi_prio	 argument  indicates  the  priority.  The priority range spans
       from 0 to 100, with 0 being the highest priority.   If  one  wishes  to
       only  alter  the SAP or priority (but not both), the current SAP can be
       retrieved using dlpi_info(3DLPI), and the default priority can be spec‐
       ified by using the DL_QOS_DONT_CARE constant.

       If the handle is in raw mode (see DLPI_RAW in dlpi_open(3DLPI)), msgbuf
       must start with the link-layer header (see dlpi(7P)). In raw mode,  the
       contents of daddrp and sendp are ignored, as they are already specified
       by the link-layer header in msgbuf.

       If msgbuf is accepted for delivery,  no	error  is  returned.  However,
       because	only  unacknowledged connectionless service (DL_CLDLS) is cur‐
       rently supported, a successful return does not guarantee that the  data
       will be successfully delivered to daddrp.

       Upon success, DLPI_SUCCESS is returned. If DL_SYSERR is returned, errno
       contains the specific UNIX system error value. Otherwise, a DLPI	 error
       value defined in <sys/dlpi.h> or an error value listed in the following
       section is returned.

			 Invalid DLPI handle

			 Invalid argument
