Function Documentation

netsnmp_mib_handler* netsnmp_get_scalar_handler (  void   )

Creates a scalar handler calling netsnmp_create_handler with a handler name defaulted to "scalar" and access method, netsnmp_scalar_helper_handler. Parameters: void  Returns: Returns a pointer to a netsnmp_mib_handler struct which contains the handler's name and the access method See also: netsnmp_get_scalar_handler netsnmp_register_scalar Definition at line 47 of file scalar.c. References netsnmp_create_handler(). Referenced by netsnmp_register_read_only_scalar(), and netsnmp_register_scalar().

int netsnmp_register_read_only_scalar (  netsnmp_handler_registration *  reginfo  )

This function registers a read only scalar helper handler. This function is very similar to netsnmp_register_scalar the only addition is that the "read_only" handler is injected into the handler chain prior to injecting the serialize handler and registering reginfo. Parameters: reginfo  a handler registration structure which could get created using netsnmp_create_handler_registration. Used to register a read only scalar helper handler. Returns: MIB_REGISTERED_OK is returned if the registration was a success. Failures are MIB_REGISTRATION_FAILURE and MIB_DUPLICATE_REGISTRATION. See also: netsnmp_register_scalar netsnmp_get_scalar_handler Definition at line 110 of file scalar.c. References netsnmp_get_instance_handler(), netsnmp_get_read_only_handler(), netsnmp_get_scalar_handler(), netsnmp_handler_registration, netsnmp_inject_handler(), netsnmp_register_serialize(), netsnmp_handler_registration_s::rootoid, and netsnmp_handler_registration_s::rootoid_len.

int netsnmp_register_scalar (  netsnmp_handler_registration *  reginfo  )

This function registers a scalar helper handler. The registered OID, reginfo->rootoid, space is extended for the instance subid using realloc() but the reginfo->rootoid_len length is not extended just yet. .This function subsequently injects the instance, scalar, and serialize helper handlers before actually registering reginfo. Each handler is injected/pushed to the top of the handler chain list and will be processed last in first out, LIFO. Parameters: reginfo  a handler registration structure which could get created using netsnmp_create_handler_registration. Used to register a scalar helper handler. Returns: MIB_REGISTERED_OK is returned if the registration was a success. Failures are MIB_REGISTRATION_FAILURE and MIB_DUPLICATE_REGISTRATION. See also: netsnmp_register_read_only_scalar netsnmp_get_scalar_handler Definition at line 75 of file scalar.c. References netsnmp_get_instance_handler(), netsnmp_get_scalar_handler(), netsnmp_handler_registration, netsnmp_inject_handler(), netsnmp_register_serialize(), netsnmp_handler_registration_s::rootoid, and netsnmp_handler_registration_s::rootoid_len.
