Detailed Description¶
Process scalars easily.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. Returns:Returns a pointer to a netsnmp_mib_handler
struct which contains the handler's name and the access method

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.

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.
