+/*
+ * NAME
+ * pkin.h - header file for readchar()
+ * SYNOPSIS
+ * #include "pkfile.h"
+ *
+ * int readchar(name, c, cd)
+ * char name[]; shalfword c; chardesc *cd;
+ * DESCRIPTION
+ * Readchar() opens the pkfile `name', checks if it's a legal pkfile,
+ * and reads the character description of `c' into `cd'. Readchar()
+ * returns TRUE (1) upon success, FALSE (0) if the character `c' is
+ * not found in the pkfile.
+ *
+ * Parameter `cd' is a pointer to a the following structure:
+ * typedef struct {
+ * integer charcode,
+ * cwidth, cheight,
+ * xoff, yoff;
+ * halfword *raster ;
+ * } chardesc ;
+ *
+ * Charcode is the code of the character returned, cwidth and cheight
+ * respectively the width and height of the character in pixels,
+ * xoff and yoff are the offsets of first pixel to the reference point
+ * of the character box.
+ * Raster is a pointer to the bitmap describing the character. This
+ * raster consists of cheight rows of (cwidth + 15) /16 words of
+ * 16 bits each. Each row contains from left to right all cwidth
+ * pixels of that row.
+ * WARNING
+ * If the machine has a default integer size of 16 bits, and 32-bit
+ * integers must be manipulated with %ld, be carefull!
+ * AUTHORS
+ * Piet Tutelaers
