Documentation
XFile. A File which could be anything.
The syntax (and results) for method is very similar
to C FILE. (Except for the FILE pointer which is not
given in the parameters!).
- XFile()
- virtual int read(void* ptr, int block_size, int n_blocks) = 0
- Read something
- virtual int write(void* ptr, int block_size, int n_blocks) = 0
- Write
- int taggedRead(void* ptr, int block_size, int n_blocks, const char* tag)
- Read and check the tag/the size. To be used with taggedWrite().
If the tag and the size readed doesn't correspond to the given
tag and size, an error will occur.
- int taggedWrite(void* ptr, int block_size, int n_blocks, const char* tag)
- Write and write the tag/the size
- virtual int eof() = 0
- Are we at the end ?
- virtual int flush() = 0
- Flush the file
- virtual int seek(long offset, int whence) = 0
- Seek
- virtual long tell() = 0
- Tell me where am I
- virtual void rewind() = 0
- Rewind
- virtual int printf(const char* format, ...) = 0
- Print some text
- virtual int scanf(const char* format, void* ptr) = 0
- Scan some text
- virtual char* gets(char* dest, int size_) = 0
- Get one line (read at most size_ characters)
