Detailed Description

MemoryWriteStream subclass with ability to set stream position indicator.

Member Function Documentation

◆ seek()

bool Common::SeekableMemoryWriteStream::seek ( int64  offset,
int  whence = SEEK_SET 
)
inlineoverridevirtual

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
offsetThe relative offset in bytes.
whenceThe seek reference: SEEK_SET, SEEK_CUR, or SEEK_END.
Returns
True on success, false in case of a failure.
