Function Documentation

bzseek()

static void bzseek ( BZFILE *  file, unsigned  offset, int    )

static

Seek on compressed input. (I hope newer libs support it directly)

Parameters

file	File handle
offset	Seek position
whence	How to seek

CanAccessFile()

bool CanAccessFile

(

const char *

filename

)

CreateFileWriter()

FileWriter* CreateFileWriter

(

const std::string &

filename

)

Create FileWriter

FindFileWithExtension()

static bool FindFileWithExtension ( char(&)  file[PATH_MAX] )

static

Find a file with its correct extension ("", ".gz" or ".bz2")

Parameters

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

Returns

true if the file has been found.

gzseek()

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

LibraryFileName() [1/2]

std::string LibraryFileName

(

const char *

file

)

Build library path name.

LibraryFileName() [2/2]

static void LibraryFileName ( const char *  file, char(&)  buffer[PATH_MAX]  )

static

Generate a filename into library.

Try current directory, user home directory, global directory. This supports .gz, .bz2 and .zip.

Parameters

file	Filename to open.
buffer	Allocated buffer for generated filename.

QuoteArguments()

std::vector<std::string> QuoteArguments

(

std::vector< std::string >

args

)

Quote arguments for usage in calls to system(), popen() and similar. Really only needed on Windows, where all these calls just concatenate all arguments with a space and pass the full string to the next process.

ReadDataDirectory()

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

Read the contents of a directory.

Generate a list of files within a specified directory

Parameters

dirname	Directory to read.
fl	Filelist pointer.

Returns

the number of entries added to FileList.

sdl_close()

static int sdl_close ( SDL_RWops *  context )

static

sdl_read()

static size_t sdl_read ( SDL_RWops *  context, void *  ptr, size_t  size, size_t  maxnum  )

static

sdl_seek()

static Sint64 sdl_seek ( SDL_RWops *  context, Sint64  offset, int  whence  )

static

sdl_size()

static Sint64 sdl_size ( SDL_RWops *  context )

static

sdl_write()

static size_t sdl_write ( SDL_RWops *  context, const void *  ptr, size_t  size, size_t  num  )

static
