Log feature (LV2_LOG__log)

Fields

handle: LV2_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: Option<unsafe extern "C" fn(handle: LV2_Log_Handle, type_: LV2_URID, fmt: *const c_char, ...) -> c_int>

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 @ref LV2_LOG__Trace.

vprintf: Option<unsafe extern "C" fn(handle: LV2_Log_Handle, type_: LV2_URID, fmt: *const c_char, ap: va_list) -> c_int>

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 @ref LV2_LOG__Trace.
