	Register a read callback for one SNMP scalar.

Detailed Description

Registers a scalar read callback with the SNMP agent.

Application code does not instantiate this class directly — use the SNMPREADFUNC macro, which constructs a file-static instance so the callback is registered before main() runs. The constructor is overloaded on every read-callback signature in Read/write callback function signatures; the compiler picks the overload that matches your getter, which in turn selects the matching ASN.1 dispatcher.

Example

snmp_typeInteger32 ReadVoltage() { return g_voltage_mv; }
SNMPREADFUNC(VOLTAGE, "1.3.6.1.4.1.8174.10.1.0", ASN_typeInteger32,
             ReadVoltage, READ_COMMUNITY_MASK);

Constructor & Destructor Documentation

SNMPReadObject()

SNMPReadObject::SNMPReadObject ( const char * oid, int typ, GetpIFunc * pf, uint32_t commmask )

inline

Register a read callback for one SNMP scalar.

Parameters

oid	Dotted-decimal OID string. Scalars end in .0.
typ	One of the ASN_type* tags (e.g. ASN_typeInteger32).
pf	Pointer to the getter; the overload chosen follows from its signature.
commmask	Community mask (typically READ_COMMUNITY_MASK).
