Member Function Documentation

pos()

virtual int64 Common::SeekableSubReadStream::pos ( ) const

inlinevirtual

Obtain the current value of the stream position indicator.

Returns

The current position indicator, or -1 if an error occurred.

Implements Common::SeekableReadStream.

Reimplemented in Common::SeekableSubReadStreamEndian.

size()

virtual int64 Common::SeekableSubReadStream::size ( ) const

inlinevirtual

Obtain the total size of the stream, measured in bytes. If this value is unknown or cannot be computed, -1 is returned.

Returns

The size of the stream, or -1 if an error occurred.

Implements Common::SeekableReadStream.

Reimplemented in Common::SeekableSubReadStreamEndian.

seek()

virtual bool Common::SeekableSubReadStream::seek ( int64  offset, int  whence = SEEK_SET  )

virtual

Set the stream position indicator for the stream.

The new position, measured in bytes, is obtained by adding offset bytes to the position specified by whence. If whence is set to SEEK_SET, SEEK_CUR, or SEEK_END, the offset is relative to the start of the file, the current position indicator, or end-of-stream, respectively. A successful call to the seek() method clears the end-of-stream indicator for the stream.

Note

The semantics of any implementation of this method is supposed to match that of ISO C fseek().

Parameters

offset	Relative offset in bytes.
whence	Seek reference: SEEK_SET, SEEK_CUR, or SEEK_END.

Returns

True on success, false in case of a failure.

Implements Common::SeekableReadStream.

Reimplemented in Common::SeekableSubReadStreamEndian.
