- * putc - 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.
- *
- * This routine is equivalent to fputc(), except that if it is implemented as
- * a macro, it may evaluate <fp> more than once; thus, the argument should
- * never be an expression with side effects.
- *
- * INCLUDE FILES: stdio.h
- *
- * RETURNS:
- * The character written, or EOF if a write error occurs, with the error
- * indicator set for the stream.
