Functions


netsnmp_mib_handler * netsnmp_get_row_merge_handler (int prefix_len)
returns a row_merge handler that can be injected into a given handler chain.
int netsnmp_register_row_merge (netsnmp_handler_registration *reginfo)
functionally the same as calling netsnmp_register_handler() but also injects a row_merge handler at the same time for you.
netsnmp_row_merge_status * netsnmp_row_merge_status_get (netsnmp_handler_registration *reginfo, netsnmp_agent_request_info *reqinfo, int create_missing)
retrieve row_merge_status
int netsnmp_row_merge_status_first (netsnmp_handler_registration *reginfo, netsnmp_agent_request_info *reqinfo)
Determine if this is the first row.
int netsnmp_row_merge_status_last (netsnmp_handler_registration *reginfo, netsnmp_agent_request_info *reqinfo)
Determine if this is the last row.
int netsnmp_row_merge_helper_handler (netsnmp_mib_handler *handler, netsnmp_handler_registration *reginfo, netsnmp_agent_request_info *reqinfo, netsnmp_request_info *requests)
Implements the row_merge handler.
void netsnmp_init_row_merge (void)
initializes the row_merge helper which then registers a row_merge handler as a run-time injectable handler for configuration file use.

Detailed Description

Calls sub handlers with request for one row at a time.

This helper splits a whole bunch of requests into chunks based on the row index that they refer to, and passes all requests for a given row to the lower handlers. This is useful for handlers that don't want to process multiple rows at the same time, but are happy to iterate through the request list for a single row.
