Function Documentation

◆ Display_syntax()

void Display_syntax ( void )

Show the command line syntax and available video modes.

◆ Error_function()

void Error_function	(	int	error_code,
		const char *	filename,
		int	line_number,
		const char *	function_name
	)

Helper function used by the macro Error.

		char *	argv[],
		char *	filenames[],
		char *	directories[],
		const char **	videomode_arg,
		int *	pixel_ratio
	)

Parse the command line.

Parameters

argc	argument count
argv	argument values
filenames	pointers to receive file names
directories	pointers to receive file directories
videomode_arg	pointer to receive the -mode argument
pixel_ratio	pointer to receive the pixel ratio requested

Returns: the number of file to open (0, 1 or 2)

Referenced by Init_program().

◆ CT_ASSERT() [1/2]

CT_ASSERT ( sizeof(T_Components) = =3 )

◆ CT_ASSERT() [2/2]

CT_ASSERT ( sizeof(T_Palette) = =768 )

◆ Init_program()

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