## Member Function Documentation

virtual const io::path& irr::io::IReadFile::getFileName | ( |  | ) | const`[pure virtual]`

Get name of file.

Returns:
  File name as zero terminated character string.

virtual long irr::io::IReadFile::getPos | ( |  | ) | const`[pure virtual]`

Get the current position in the file.

Returns:
  Current position in the file in bytes.

virtual long irr::io::IReadFile::getSize | ( |  | ) | const`[pure virtual]`

Get size of file.

Returns:
  Size of the file in bytes.

virtual s32 irr::io::IReadFile::read | ( | void * | buffer,
|  | u32 | sizeToRead |
| ) |  |  | `[pure virtual]`

Reads an amount of bytes from the file.

Parameters:

  | buffer | Pointer to buffer where read bytes are written to.
  | sizeToRead | Amount of bytes to read from the file.

Returns:
  How many bytes were read.

virtual bool irr::io::IReadFile::seek | ( | long | finalPos,
|  | bool | relativeMovement = `false` |
| ) |  |  | `[pure virtual]`

Changes position in file.

Parameters:

  | finalPos | Destination position in the file.
  | relativeMovement | If set to true, the position in the file is changed relative to current position. Otherwise the position is changed from beginning of file.

Returns:
  True if successful, otherwise false.
