Typedef Documentation

◆ log_line_processor

typedef bool(* log_line_processor) (log_line *ll)

This defines built-in functions for use by logging services.

These helpers are organized into a number of APIs grouping related functionality.

For documentation of the individual functions, see log_builtins.cc typedef for log-processing functions ("buffer this event", "process this event", etc.)

◆ mysql_service_log_builtins_string_t

String primitives for logging services.

◆ mysql_service_log_builtins_syseventlog_t

Syslog/Eventlog functions for logging services.

◆ mysql_service_log_builtins_t

Primitives for services to interact with the structured logger: functions pertaining to log_line and log_item data.

◆ mysql_service_log_builtins_tmp_t

Temporary primitives for logging services.

Function Documentation

◆ log_line_process_hook_get()

log_line_processor log_line_process_hook_get ( void  )

Get current log-event processor.

When a log-event is submitted, a function is applied to that event. That function usually either buffers the event for later processing, or filters and logs the event. log_line_process_hook_get() returns a pointer to that function.

Return values
apointer to a log-event processing function

◆ log_line_process_hook_set()

void log_line_process_hook_set ( log_line_processor  llp)

Set the log-event processor.

When a log-event is submitted, a function is applied to that event. That function usually either buffers the event for later processing, or filters and logs the event.

That function can be set here.

Parameters
llpA log-processor
