Function Documentation

main()

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

The main function of para_filter.

Para_filter reads data from stdin, converts it by using a chain of filters (specified on the command line) and writes the resulting data to stdout.

Parameters

argc	Number of command line options.
argv	Vector of arguments.

Returns

EXIT_SUCCESS on success, EXIT_FAILURE on errors.

Variable Documentation

DEFINE_PARA_ERRLIST

DEFINE_PARA_ERRLIST

Array of error strings.

status_item_list

const char* status_item_list[] = {STATUS_ITEMS}

The list of all status items used by para_{server,audiod,gui}.

status items

stat_item_values

char* stat_item_values[NUM_STAT_ITEMS] = {NULL}

Dummy version which only contains NULL pointers.

The array of status items sent by para_server.

This is used by the amp filter which first tries to obtain the amplification value from an element in this array.

para_log

__printf_2_3 void(* para_log) (int, const char *,...) = stderr_log
