Several library modules are provided in source code form. These routines are used to perform low level hardware related I/O for the stream I/O functions. You can find the source for these routines in the \C251\LIB directory. You may modify these source files and substitute them for the library routines.

By using these routines, you can quickly adapt the library to perform (using any hardware I/O device available in your target) stream I/O. Refer to Stream I/O Routines for more information.
