Field Documentation

◆ handle

LV2_Log_Handle LV2_Log_Log::handle

Opaque pointer to host data.

This MUST be passed to methods in this struct whenever they are called. Otherwise, it must not be interpreted in any way.

◆ printf

int(* LV2_Log_Log::printf) (LV2_Log_Handle handle, LV2_URID type, const char *fmt,...)

Log a message, passing format parameters directly.

The API of this function matches that of the standard C printf function, except for the addition of the first two parameters. This function may be called from any non-realtime context, or from any context if type is LV2_LOG__Trace.

◆ vprintf

int(* LV2_Log_Log::vprintf) (LV2_Log_Handle handle, LV2_URID type, const char *fmt, va_list ap)

Log a message, passing format parameters in a va_list.

The API of this function matches that of the standard C vprintf function, except for the addition of the first two parameters. This function may be called from any non-realtime context, or from any context if type is LV2_LOG__Trace.
