gsklogringbuffer a line-oriented fixed-length ring buffer GskLogRingBuffer provides a very efficient way to keep track of the last N bytes of text data. Typically, this is used for logs that change too fast to justify keeping them in a file, but which are useful for getting status and debugging. Create a new ring buffer. It will never contain more that @size bytes of data. @size: the maximum number of bytes of data to buffer. @Returns: the newly allocated ring-buffer. Append text to the ring-buffer. It the text is too long, earlier lines may be erased. The text should NOT end with a newline-- one will be added by this function. @buffer: the buffer to affect. @line: the line to append. Get the entire ring-buffer as a newly allocated string. @buffer: the buffer to query. @Returns: the newly allocated NUL-terminated string of the last text added to the buffer, as whole lines. Free the ring-buffer. @buffer: the buffer to free.
