Default constructor.
Member Function Documentation
|
virtual |
Return the size of the stream.
- Returns
- The total number of bytes available in the stream, or -1 on error
Implements sf::InputStream.
| 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
|
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.
|
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.
|
virtual |
Get the current reading position in the stream.
- Returns
- The current position, or -1 on error.
Implements sf::InputStream.
