    1.29 +<<putc>>---write a character (macro)

    1.31 +INDEX
    1.32 +	putc
    1.33 +
    1.34 +ANSI_SYNOPSIS
    1.35 +	#include <stdio.h>
    1.36 +	int putc(int <[ch]>, FILE *<[fp]>);
    1.37 +
    1.38 +TRAD_SYNOPSIS
    1.39 +	#include <stdio.h>
    1.40 +	int putc(<[ch]>, <[fp]>)
    1.41 +	int <[ch]>;
    1.42 +	FILE *<[fp]>;
    1.43 +
    1.44 +DESCRIPTION
    1.45 +<<putc>> is a macro, defined in <<stdio.h>>.  <<putc>>
    1.46 +writes the argument <[ch]> to the file or stream identified by
    1.47 +<[fp]>, after converting it from an <<int>> to an <<unsigned char>>.
    1.48 +
    1.49 +If the file was opened with append mode (or if the stream cannot
    1.50 +support positioning), then the new character goes at the end of the
    1.51 +file or stream.  Otherwise, the new character is written at the
    1.52 +current value of the position indicator, and the position indicator
    1.53 +advances by one.
    1.54 +
    1.55 +For a subroutine version of this macro, see <<fputc>>.
    1.56 +
    1.57 +RETURNS
    1.58 +If successful, <<putc>> returns its argument <[ch]>.  If an error
    1.59 +intervenes, the result is <<EOF>>.  You can use `<<ferror(<[fp]>)>>' to
    1.60 +query for errors.
    1.61 +
    1.62 +PORTABILITY
    1.63 +ANSI C requires <<putc>>; it suggests, but does not require, that
    1.64 +<<putc>> be implemented as a macro.  The standard explicitly permits
    1.65 +macro implementations of <<putc>> to use the <[fp]> argument more than once;
    1.66 +therefore, in a portable program, you should not use an expression
    1.67 +with side effects as this argument.
    1.68 +
    1.69 +Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
    1.70 +<<lseek>>, <<read>>, <<sbrk>>, <<write>>.
