static int FindFileWithExtension	(	char *	file,
		size_t	filesize
	)			[static]

Find a file with its correct extension ("" or ".gz")

Parameters:

	file	The string with the file path. Upon success, the string is replaced by the full filename witht he correct extension.
	filesize	Size of the file buffer

Returns:

1 if the file has been found.

static int gzseek	(	CFile *	file,
		unsigned	offset,
		int	whence
	)			[static]

Seek on compressed input. (Newer libs support it directly)

Parameters:

	file	File
	offset	Seek position
	whence	How to seek

char* LibraryFileName	(	const char *	file,
		char *	buffer,
		size_t	buffersize
	)

< Build libary path name

Generate a filename into library.

Try current directory, user home directory, global directory.

Parameters:

	file	Filename to open.
	buffer	Allocated buffer for generated filename.
	buffersize	Size of the buffer

Returns:

Pointer to buffer.

int ReadDataDirectory	(	const char *	dirname,
		int(*)(char *, FileList *)	filter,
		std::vector< FileList > &	fl
	)

Generate a list of files within a specified directory

Parameters:

	dirname	Directory to read.
	filter	Optional xdata-filter function.
	fl	Filelist pointer.

Returns:

the number of entries added to FileList.
