* Description:
sl@0
    15
* FUNCTION
sl@0
    16
* <<fputc>>---write a character on a stream or file
sl@0
    17
* INDEX
sl@0
    18
* fputc
sl@0
    19
* ANSI_SYNOPSIS
sl@0
    20
* #include <stdio.h>
sl@0
    21
* int fputc(int <[ch]>, FILE *<[fp]>);
sl@0
    22
* TRAD_SYNOPSIS
sl@0
    23
* #include <stdio.h>
sl@0
    24
* int fputc(<[ch]>, <[fp]>)
sl@0
    25
* int <[ch]>;
sl@0
    26
* FILE *<[fp]>;
sl@0
    27
* <<fputc>> converts the argument <[ch]> from an <<int>> to an
sl@0
    28
* <<unsigned char>>, then writes it to the file or stream identified by
sl@0
    29
* <[fp]>.
sl@0
    30
* If the file was opened with append mode (or if the stream cannot
sl@0
    31
* support positioning), then the new character goes at the end of the
sl@0
    32
* file or stream.  Otherwise, the new character is written at the
sl@0
    33
* current value of the position indicator, and the position indicator
sl@0
    34
* advances by one.
sl@0
    35
* For a macro version of this function, see <<putc>>.
sl@0
    36
* RETURNS
sl@0
    37
* If successful, <<fputc>> returns its argument <[ch]>.  If an error
sl@0
    38
* intervenes, the result is <<EOF>>.  You can use `<<ferror(<[fp]>)>>' to
sl@0
    39
* query for errors.
sl@0
    40
* PORTABILITY
sl@0
    41
* <<fputc>> is required by ANSI C.
sl@0
    42
* Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
sl@0
    43
* <<lseek>>, <<read>>, <<sbrk>>, <<write>>.
