+FUNCTION
+<<putc>>---write a character (macro)
+
+INDEX
+	putc
+
+ANSI_SYNOPSIS
+	#include <stdio.h>
+	int putc(int <[ch]>, FILE *<[fp]>);
+
+TRAD_SYNOPSIS
+	#include <stdio.h>
+	int putc(<[ch]>, <[fp]>)
+	int <[ch]>;
+	FILE *<[fp]>;
+
+DESCRIPTION
+<<putc>> is a macro, defined in <<stdio.h>>.  <<putc>>
+writes the argument <[ch]> to the file or stream identified by
+<[fp]>, after converting it from an <<int>> to an <<unsigned char>>.
+
+If the file was opened with append mode (or if the stream cannot
+support positioning), then the new character goes at the end of the
+file or stream.  Otherwise, the new character is written at the
+current value of the position indicator, and the position indicator
+advances by one.
+
+For a subroutine version of this macro, see <<fputc>>.
+
+RETURNS
+If successful, <<putc>> returns its argument <[ch]>.  If an error
+intervenes, the result is <<EOF>>.  You can use `<<ferror(<[fp]>)>>' to
+query for errors.
+
+PORTABILITY
+ANSI C requires <<putc>>; it suggests, but does not require, that
+<<putc>> be implemented as a macro.  The standard explicitly permits
+macro implementations of <<putc>> to use the <[fp]> argument more than once;
+therefore, in a portable program, you should not use an expression
+with side effects as this argument.
+
+Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
+<<lseek>>, <<read>>, <<sbrk>>, <<write>>.
