Detailed Description

Easy2D has a set of subsystems working together to help you run your game application. These subsystems are all singletons, but they may be accessed via these Utilities for convenience. Also, in here are some static methods that were useful inside the engine, and may be useful for your application as well.

Member Function Documentation

void e2d::core::Utilities::GetTextFromFile	(	char **	text,
		const char *	filename
	)			[static]

Reads the whole text file and puts its contents into the char pointer passed as parameter. The resulting string is null-terminated.

Parameters:

	text	Pointer to char where the contents of the file will be stored.
	filename	Path to the text file.

Exceptions:

Exception

if file opening fails.

void e2d::core::Utilities::UnGZip	(	const char *	from,
		int	fromlen,
		const char *	to,
		int	maxlen
	)			[static]

Inflates a gzip compressed string into another string. The "to" pointer must be already allocated, and you must inform its maximum size in bytes to the decompressing method.

Note:

This method uses zlib for decompression.

Parameters:

	from	Compressed string.
	fromlen	Compressed string length, in bytes.
	to	Pointer to decompressed string, must be pre-allocated.
	maxlen	Decompressed maximum string length, in bytes.

Exceptions:

Exception

if any decompressing error occurs. See zlib.h for error descriptions.
