MemoryInputStream()

sf::MemoryInputStream::MemoryInputStream

(

)

Default constructor.

Member Function Documentation

getSize()

virtual Int64 sf::MemoryInputStream::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.

open()

void sf::MemoryInputStream::open	(	const void *	data,
		std::size_t	sizeInBytes )

Open the stream from its data.

Parameters

data	Pointer to the data in memory
sizeInBytes	Size of the data, in bytes

read()

virtual Int64 sf::MemoryInputStream::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

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

Returns

The number of bytes actually read, or -1 on error

Implements sf::InputStream.

seek()

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

virtual

Change the current reading position.

Parameters

position

The position to seek to, from the beginning

Returns

The position actually sought to, or -1 on error

Implements sf::InputStream.

tell()

virtual Int64 sf::MemoryInputStream::tell ( )

virtual

Get the current reading position in the stream.

Returns

The current position, or -1 on error.

Implements sf::InputStream.
