/* Specialized SNMP error category log/err callback
*
* This function displays all negative SNMP errors on the form SNMPERR_* that are not SNMPERR_SUCCESS(=0)
* There are also positive SNMP errors on the form SNMP_ERR_* which are not properly handled below
* @param[in] handle Application-specific handle
* @param[in] suberr Application-specific handle, points to SNMP_ERR_* unless < -0x1000 in which
case they are MIB_* errors defined in agent_registry.h
* @param[out] cb Read log/error string into this buffer
* @note Some SNMP API functions sometimes returns NULL/ptr or other return values that do not fall into
* this category, then OE_SNMP should NOT be used.
