virtual

Default destructor.

Member Function Documentation

virtual Int64 sf::FileInputStream::getSize ( )
virtual

Return the size of the stream.

Returns
The total number of bytes available in the stream, or -1 on error

Implements sf::InputStream.

bool sf::FileInputStream::open ( const std::string &  filename)

Open the stream from a file path.

Parameters
filenameName of the file to open
Returns
True on success, false on error
virtual Int64 sf::FileInputStream::read ( void *  data,
Int64  size 
)
virtual

Read data from the stream.

After reading, the stream's reading position must be advanced by the amount of bytes read.

Parameters
dataBuffer where to copy the read data
sizeDesired number of bytes to read
Returns
The number of bytes actually read, or -1 on error

Implements sf::InputStream.

virtual Int64 sf::FileInputStream::seek ( Int64  position)
virtual

Change the current reading position.

Parameters
positionThe position to seek to, from the beginning
Returns
The position actually sought to, or -1 on error

Implements sf::InputStream.

virtual Int64 sf::FileInputStream::tell ( )
virtual

Get the current reading position in the stream.

Returns
The current position, or -1 on error.

Implements sf::InputStream.
