NAME
       send_easy_trap, send_trap_vars, send_v2trap - send TRAPs or INFORMs from a Net-SNMP MIB module

SYNOPSIS
       #include <net-snmp/agent/agent_trap.h>

       void send_easy_trap(int trap, int specific);

       void send_trap_vars(int trap, int specific, struct variable_list *vars);

       void send_v2trap(struct variable_list *vars);

DESCRIPTION
       These three routines may be used to send traps from a MIB module within the Net-SNMP agent (including an AgentX subagent).

       send_easy_trap()  sends	an SNMPv1 trap (or the SNMPv2 equivalent) to the list of configured trap destinations (or "sinks"), using the pro-
       vided values for the generic trap type, and specific trap value.

       send_trap_vars() is similar, but appends the supplied list of variable bindings to the traps that are sent.

       send_v2trap() uses the supplied list of variable bindings to form an SNMPv2 trap, which is sent to SNMPv2-capable sinks on  the	configured
       list.  An equivalent INFORM is sent to the configuredq list of inform sinks.  Sinks that can only handle SNMPv1 traps are skipped.

       The  various "send_trap()" calls allow you to specify traps in different formats.  And the various "trapsink" directives allow you to spec-
       ify destinations to receive different formats.  But *all* traps are sent to *all* destinations, regardless of how they were specified.
       I.e. it's
						___  trapsink
					       /
	   send_easy_trap ___  [  Trap	    ] ____  trap2sink
			   ___	[ Generator  ]
	   send_v2trap	  /	[	     ] ----- informsink
					       ____
						     trapsess

       *Not*
	    send_easy_trap  ------------------->  trapsink
	    send_v2trap     ------------------->  trap2sink
	    ????	    ------------------->  informsink
	    ????	    ------------------->  trapsess

WARNINGS
       These routines are used to send the traps immediately they are called.  Invoking them at the appropriate time is left  to  the  MIB  module
       programmer.
