//    5  * This is a template implementation of the "__read" function used by
//    6  * the standard library.  Replace it with a system-specific
//    7  * implementation.
//    8  *
//    9  * The "__read" function reads a number of bytes, at most "size" into
//   10  * the memory area pointed to by "buffer".  It returns the number of
//   11  * bytes read, 0 at the end of the file, or _LLIO_ERROR if failure
//   12  * occurs.
//   13  *
//   14  * The template implementation below assumes that the application
//   15  * provides the function "MyLowLevelGetchar".  It should return a
//   16  * character value, or -1 on failure.
//   17  *
