EvmEventPost(3)						       EvmEventPost(3)

       EvmEventPost(), EvmEventPostVa() - post an EVM event

       EVM Support Library

       connection    The  connection through which events are posted. See Evm‐

       event	     The event that is to be posted to the  specified  connec‐
		     tion. See EvmEventCreate(3).

       item_id	     The  identifier  for  the	event data item to be set. See
		     EvmItemSet(3) for possible values for this	 operand,  and
		     the data contained by the data item.

       item_value    The  value	 to be stored in the associated item indicated
		     by item_id.

       An EVM client program uses the routines described on this page to  pass
       events to the EVM daemon, for distribution to subscribers.

       posts an event that has already been created with or

       creates,	 posts	and destroys an event in a single call.	 It first cre‐
       ates a new event, adding any data items supplied in the call to it.  If
       the  event  operand is not NULL, the contents of the supplied event are
       then merged into the new event, and the new event is posted.   The  new
       event  is  destroyed before the routine returns, and the supplied event
       (if any) is unchanged.  See EvmItemSetVa(3) for details of the item_ids
       and item_values that may be passed as operands to this routine.

       If  NULL	 is  passed  as the connection operand to either of these rou‐
       tines, the event is posted to the local daemon using a  temporary  con‐
       nection.	  The  temporary  connection  is  destroyed before the routine
       returns.	 Because of the overhead associated with creating and destroy‐
       ing  an	EVM  connection,  pass	NULL only if your program rarely posts

       If either routine is unable to pass the event to the daemon, the	 error
       is  reported  immediately  through  the	return	code.  If the event is
       passed to the daemon, the type of response depends on the response mode
       specified when the connection was created.

	      1. These	routines  do not destroy the event passed as the event
		 operand.  Explicitly call to destroy the event and  free  its
		 memory once it is no longer needed.

	      2. Avoid	posting	 a large number of events in rapid succession,
		 since this may cause the connection's send  buffer  to	 fill,
		 and  the  posting  process  to block until the EVM daemon has
		 relieved some or all of the data. Although this is  a	normal
		 part  of  process synchronization, some high-performance pro‐
		 cesses may prefer to block as infrequently as possible.   can
		 be used to increase the size of the send buffer.  See EvmCon‐
		 nControl(3) for more information.

	      3. When using extended item_ids to supply names  and  values  of
		 variable items to be sure to supply the correct number of op‐
		 erands for each.  A variable name and value is	 required  for
		 all such items, and some variable types require an additional
		 argument. See EvmItemSetVa(3) for more information.

       The operation completed without error.

       The EVM daemon rejected the event.
	      The most likely reasons are that no template has been registered
	      for  the event, or that the caller is not authorized to post the
	      event. See evmtemplate(4) and evm.auth(4) for more information.

       One of the arguments to the function is invalid.

       A value in a structure member is invalid.

       An operation failed because an attempt to acquire heap memory failed.

       The connection's output buffer is full, and the event has
	      been queued in heap space.  Another attempt is made to flush the
	      queue  when  the next call is made to or when the caller invokes
	      This error code is only returned for connections for  which  has
	      been invoked with the request argument set to

       A read error occurred while reading from the EVM daemon connection.
	      The  connection is no longer usable.  The caller needs to invoke
	      to destroy it.

       A write error occurred while writing to the EVM daemon connection.
	      The connection is no longer usable.  The caller needs to	invoke
	      to destroy it.

       The value of is not set.
