A method and apparatus assists communication between a writer of a shared file and the reader of the shared file without requiring the use of a shared file. When the writer fills a buffer with information and provides a write commend to write the buffer to a shared file, the buffer is not written to a file. Instead, the pointer to the buffer is passed to the reader, and the writer may be suspended until the reader indicates it has read the file. Alternately, two buffers may be used, with the contents of the buffer used by the writer copied to a second buffer, allowing the writer to reuse the first buffer before the reader has completed reading the contents of the second buffer.
