unsigned filter_collect	(	int	argc,
		char **	argv
	)

If a filter argument is present on the command line use it to construct a bit mask of components to write out.

Parameters:

	argc	Number of command line arguments
	argv	Array of command line arguments

Returns:

A bit mask of the components to write out

unsigned get_bit

(

char *

type

)

Lookup the type and return a one-bit bit mask with the corresponding bit set.

Parameters:

type

NULL terminated LATC type name

Returns:

Bit mask with the bit corresponding to type set.

void input_collect	(	int	argc,
		char **	argv,
		char **	list
	)

Set the elements of the list array to be pointers to NULL terminated filenames.

Parameters:

	argc	Number of command line arguments
	argv	Array of command line arguments
	list	Array of pointers to the filenames

unsigned input_count	(	int	argc,
		char **	argv
	)

Count the number of input files.

Parameters:

	argc	Number of command line arguments
	argv	Array of command line arguments

Returns:

Number of comma separated filenames in the input argument

char* output_collect	(	int	argc,
		char **	argv
	)

Locate the output stub string in the command line arguments.

Parameters:

	argc	Number of command line arguments
	argv	Array of command line arguments

Returns:

Pointer to the output stub string

unsigned verbose_collect	(	int	argc,
		char **	argv
	)

Check the command line arguments for the verbose flag.

Parameters:

	argc	Number of command line arguments
	argv	Array of command line arguments

Return values:

	0	If -v is not one of the command line arguments
	1	If -v is one of the command line arguments
