Detailed Documentation

An implementation for a zip file steam.

Construction

IOStreamPak(Pak* pack, const std::string& path, bool writeMode = false)

Open a file from a zip file.

Parameters:

pack	Pack to open from path
path	Path of the file in the pack file
writeMode	Set true if the PAK is in write mode

Methods

virtual ios_size read(char* data, ios_size size)

Read data from the stream.

Parameters:

data	Buffer where to copy the read data
size	Desired number of bytes to read

Returns:

The number of bytes actually read

virtual ios_size write(const char* data, ios_size size)

Write data to the virtual file.

Parameters:

data	Data to write in the file
size	Size of the data that needs to be writed

virtual ios_size seek(ios_size position)

Change the current reading position.

Parameters:

position

The position to seek to, from the beginning

Returns:

The position actually sought to.

virtual ios_size tell()

Get the current reading position in the stream.

Returns:

The current position, or -1 on error.

virtual ios_size getSize()

Return the size of the stream.

Returns:

The total number of bytes available in the stream

virtual bool isOpen()

Returns:

If the virtual stream file is open
