NETSNMP_TRAP_API(3)                Net-SNMP                NETSNMP_TRAP_API(3)


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 provided
       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 specify
       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.
