-Placeholder
+Putc add the character "ch" to the file "fp" at the current
+writing position and advances the position pointer.
+</para>
+<para>
+Putchar is implemented as a macro (defined in the header file)
+and is equivalent to "putc(ch,stdout)".
+</para>
+<para>
+Putw adds the (two byte) machine word "n" to the file "fp" in
+the manner of putc.
+</para>
+<para>
+Output via putc is normally buffered except;
+(a) when the buffering is disabled by "setbuf()", and
+(b) the standard error output is always unbuffered.
