Member Function Documentation

◆ size()

int64 PosixIoStream::size ( ) const
overridevirtual

Obtain the current 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::SeekableWriteStream.
