Typedef Documentation

mixer_subcommand_handler_t

typedef int(* mixer_subcommand_handler_t) (const struct mixer *)

Function Documentation

main()

int main	(	int	argc,
		char *	argv[]
	)

The main function of para_mixer.

The executable is linked with the alsa or the oss mixer API, or both. It has a custom log function which prefixes log messages with the current date.

Parameters

argc	Argument counter.
argv	Argument vector.

Returns

EXIT_SUCCESS or EXIT_FAILURE.
