BloombergLP::ball::RecordBuffer::pushFront

Insert the specified handle at the front of this record buffer. Return 0 on success, and a non‐zero value otherwise. Note that concrete implementations are permitted to remove records from the buffer in order to attempt to accommodate a pushFront request (which implies that, after a successful call to pushFront, length is not guaranteed to be more than one, and an unsuccessful call to pushFront is permitted to leave the buffer empty).
