Suzanne O'Hara <sohara@lamont.ldgo.columbia.edu> asks:

	I am learning to program with motif and have run into what
	seems a very simple problem. I have not been able to find a way
	to convert a motif XmString to a regular C char string.

This should work:

----- cut here -----

#include <Xm/Xm.h>

char	*
XmStringGet(w, str)
	Widget		w;	/* widget that owns the XmString */
	XmString	str;	/* the XmString itself */
{
	char			*text, *buf;
	Boolean			sep;
	XmStringContext		context;
	XmStringDirection	dir;
	XmStringCharSet		set;

	if (XmStringInitContext(&context, str) == FALSE) {
		XtAppWarning(XtWidgetToApplicationContext(w),
		    "couldn't initialize context!\n");
		return((char *)NULL);
	}

	buf = (char *)NULL;

	while (XmStringGetNextSegment(context, &text, &set, &dir, &sep))  {
		if (sep)
			break;
		if (text == (char *)NULL || *text == (char)NULL)
			continue;
		if (buf) {
			buf = XtRealloc(buf, strlen(buf) + strlen(text) + 2);
			(void)strcat(buf, text);
		} else
			buf = XtNewString(text);
	}

	XmStringFreeContext(context);
	return(buf);
}
