Protocol for drivers that receive log output from the core.
class LogDriver[source]

Bases: Protocol

Protocol for drivers that receive log output from the core.

Cores request logging via RETRO_ENVIRONMENT_GET_LOG_INTERFACE.

retro_log_callback

The C callback struct whose log function pointer this protocol implements.

abstractmethod log(level, fmt)[source]

Emit a log message from the core.

Corresponds to retro_log_printf_t.

Warning

retro_log_printf_t normally has printf-style variadic arguments, but ctypes doesn’t currently support variadic callbacks.

As a workaround, your Core can format log messages with sprintf or similar, then pass it as the format string.

Parameters:

  • level (LogLevel) – The severity of the message.

  • fmt (bytes) – The message as a null-terminated byte string.
