+FUNCTION
+<<putchar>>---write a character (macro)
+
+INDEX
+	putchar
+INDEX
+	_putchar_r
+
+ANSI_SYNOPSIS
+	#include <stdio.h>
+	int putchar(int <[ch]>);
+
+	int _putchar_r(void *<[reent]>, int <[ch]>);
+
+TRAD_SYNOPSIS
+	#include <stdio.h>
+	int putchar(<[ch]>)
+	int <[ch]>;
+
+	int _putchar_r(<[reent]>, <[ch]>)
+	char *<[reent]>;
+	int <[ch]>;
+
+DESCRIPTION
+<<putchar>> is a macro, defined in <<stdio.h>>.  <<putchar>>
+writes its argument to the standard output stream,
+after converting it from an <<int>> to an <<unsigned char>>.
+
+The alternate function <<_putchar_r>> is a reentrant version.  The
+extra argument <[reent]> is a pointer to a reentrancy structure.
+
+RETURNS
+If successful, <<putchar>> returns its argument <[ch]>.  If an error
+intervenes, the result is <<EOF>>.  You can use `<<ferror(stdin)>>' to
+query for errors.
+
+PORTABILITY
+ANSI C requires <<putchar>>; it suggests, but does not require, that
+<<putchar>> be implemented as a macro.
+
+Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
+<<lseek>>, <<read>>, <<sbrk>>, <<write>>.
