old_api: Calls mib module code written in the old style of code.(3)

NAME
old_api: Calls mib module code written in the old style of code. - This is a backwards compatilibity module that allows code written in the old API to be run under the new handler based architecture.

  Functions
netsnmp_mib_handler * get_old_api_handler (void)
returns a old_api handler that should be the final calling handler.
int netsnmp_register_old_api (const char *moduleName, struct variable *var, size_t varsize, size_t numvars, oid *mibloc, size_t mibloclen, int priority, int range_subid, oid range_ubound, netsnmp_session *ss, const char *context, int timeout, int flags)
Registers an old API set into the mib tree.
int netsnmp_register_mib_table_row (const char *moduleName, struct variable *var, size_t varsize, size_t numvars, oid *mibloc, size_t mibloclen, int priority, int var_subid, netsnmp_session *ss, const char *context, int timeout, int flags)
registers a row within a mib table
int netsnmp_old_api_helper (netsnmp_mib_handler *handler, netsnmp_handler_registration *reginfo, netsnmp_agent_request_info *reqinfo, netsnmp_request_info *requests)
implements the old_api handler

Detailed Description

This is a backwards compatilibity module that allows code written in the old API to be run under the new handler based architecture. Use it by calling netsnmp_register_old_api().

Function Documentation

  netsnmp_mib_handler* get_old_api_handler (void)

returns a old_api handler that should be the final calling handler. Don't use this function. Use the netsnmp_register_old_api() function instead. Definition at line 40 of file old_api.c.

Registers an old API set into the mib tree. Functionally this mimics the old register_mib_context() function (and in fact the new register_mib_context() function merely calls this new old_api one). netsnmp_handler_registration_free(reginfo); already freed Definition at line 51 of file old_api.c.
