* fputc - write a character to a stream (ANSI)
*
* This routine writes a character <c> to a specified stream, at the
* position indicated by the stream's file position indicator
* (if defined), and advances the indicator appropriately.
*
* If the file cannot support positioning requests, or if the stream was opened 
* in append mode, the character is appended to the output stream.
* 
* INCLUDE FILES: stdio.h 
*
* RETURNS:
* The character written, or EOF if a write error occurs, with the error
* indicator set for the stream.
