Function Documentation¶
netsnmp_mib_handler* netsnmp_get_instance_handler
(void)¶
Creates an instance helper handler, calls netsnmp_create_handler, which then
could be registered, using
netsnmp_register_handler().
Returns:
Returns a pointer to a netsnmp_mib_handler
struct which contains the handler's name and the access method

int netsnmp_instance_num_file_handler (netsnmp_mib_handler

requests)¶

Definition at line 741 of file instance.c.
int netsnmp_register_instance
(netsnmp_handler_registration * reginfo)¶
This function registers an instance helper handler, which is a way of
registering an exact OID such that GENEXT requests are handled entirely by the
helper. First need to inject it into the calling chain of the handler defined
by the netsnmp_handler_registration struct, reginfo. The new handler is
injected at the top of the list and will be the new handler to be called
first. This function also injects a serialize handler before actually calling
netsnmp_register_handle, registering reginfo.
Parameters:
reginfo a handler registration
structure which could get created using netsnmp_create_handler_registration.
Used to register an instance helper handler.
Returns:
MIB_REGISTERED_OK is returned if the
registration was a success. Failures are MIB_REGISTRATION_FAILED and
MIB_DUPLICATE_REGISTRATION.
Examples:
delayed_instance.c.
Definition at line 73 of file instance.c.
int netsnmp_register_int_instance (const char * name, oid *
reg_oid, size_t reg_oid_len, int * it, Netsnmp_Node_Handler * subhandler)¶
This function registers an int helper handler to a specified OID.
Parameters:
name the name used for registration
pruposes.
reg_oid the OID where you want to register your integer at
reg_oid_len the length of the OID
it the integer value to be registered during initialization
subhandler a handler to do whatever you want to do, otherwise use NULL to
use the default int handler.
Returns:
MIB_REGISTERED_OK is returned if the
registration was a success. Failures are MIB_REGISTRATION_FAILED and
MIB_DUPLICATE_REGISTRATION.
Examples:
scalar_int.c.
Definition at line 460 of file instance.c.
int netsnmp_register_read_only_instance
(netsnmp_handler_registration * reginfo)¶
This function injects a 'read only' handler into the handler chain prior to
serializing/registering the handler. The only purpose of this 'read only'
handler is to return an appropriate error for any requests passed to it in a
SET mode. Inserting it into your handler chain will ensure you're never asked
to perform a SET request so you can ignore those error conditions.
Parameters:
reginfo a handler registration
structure which could get created using netsnmp_create_handler_registration.
Used to register a read only instance helper handler.
Returns:
MIB_REGISTERED_OK is returned if the
registration was a success. Failures are MIB_REGISTRATION_FAILED and
MIB_DUPLICATE_REGISTRATION.
Definition at line 100 of file instance.c.
