Base class of most objects of the Irrlicht Engine.
Interface providing read acess to a file.
Definition IReadFile.h:18
virtual long getSize() const =0
Get size of file.
virtual const io::path & getFileName() const =0
Get name of file.
virtual s32 read(void *buffer, u32 sizeToRead)=0
Reads an amount of bytes from the file.
virtual bool seek(long finalPos, bool relativeMovement=false)=0
Changes position in file.
virtual long getPos() const =0
Get the current position in the file.
File containing useful basic utility functions.
