    14 * Description:
    15 * FUNCTION
    16 * <<fputc>>---write a character on a stream or file
    17 * INDEX
    18 * fputc
    19 * ANSI_SYNOPSIS
    20 * #include <stdio.h>
    21 * int fputc(int <[ch]>, FILE *<[fp]>);
    22 * TRAD_SYNOPSIS
    23 * #include <stdio.h>
    24 * int fputc(<[ch]>, <[fp]>)
    25 * int <[ch]>;
    26 * FILE *<[fp]>;
    27 * <<fputc>> converts the argument <[ch]> from an <<int>> to an
    28 * <<unsigned char>>, then writes it to the file or stream identified by
    29 * <[fp]>.
    30 * If the file was opened with append mode (or if the stream cannot
    31 * support positioning), then the new character goes at the end of the
    32 * file or stream.  Otherwise, the new character is written at the
    33 * current value of the position indicator, and the position indicator
    34 * advances by one.
    35 * For a macro version of this function, see <<putc>>.
    36 * RETURNS
    37 * If successful, <<fputc>> returns its argument <[ch]>.  If an error
    38 * intervenes, the result is <<EOF>>.  You can use `<<ferror(<[fp]>)>>' to
    39 * query for errors.
    40 * PORTABILITY
    41 * <<fputc>> is required by ANSI C.
    42 * Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
    43 * <<lseek>>, <<read>>, <<sbrk>>, <<write>>.
