 Sfio is a portable library for managing I/O streams. It provides similar
 functionality to the ANSI C Standard I/O functions known collectively as
 Stdio. However, it has a distinct interface and is generally faster and
 more robust than most Stdio implementations. Sfio also introduces a number
 of new features and concepts beyond Stdio stream I/O processing:
 .
  * Automatic locking to avoid concurrent stream accesses,
  * I/O disciplines to pre/post-process read/write data from/to streams,
  * Stream stacking for recursive processing of nested streams,
  * Stream pooling for automatic stream synchronization when I/O operations
    are performed on different streams,
  * Buffer reservation for safe access to the internal buffers of streams,
  * Robust handling of variable-sized records, and
  * Extensible printf/scanf-like formatting I/O operations.
