/* Example 6a. How to specify annotations during a */
/* simple alteration. */
/* In order to specify annotations to an object */
/* during a simple alteration, the annotations must */
/* be specified between time the alteration is */
/* initiated and the time the data is written into */
/* an object. (Assume an empty file.) */
#include <stdlib.h>
#include "gfcursor.hpp"
int main(void) {
char newchar = 'u';
int valid;
CURSOR *c = new CURSOR("newfile");
c>eCursorQueryValid(&valid);
if (!valid)
exit(1);
c>eCursorMoveIn();
c>eCursorMovePreFirst();
c>eAltAppend();
c>eObjSetComment("Response to question #1");
c>eObjSetClass(144);
c>eObjWrite(newchar);
delete c;
return 0;
}
/* Ending file layout: */
/* { } */
/* ['u':CO("Response to question #1"):CL(144)] */
/* The above code associated the comment and class */
/* number with the object containing the character */
/* value 'u'. Each type of annotation can only be */
/* specified once within a single alteration. Once an */
/* annotation has been specified in an alteration, any */
/* subsequent attempts to set that alteration will be */
/* ignored unless the programmer calls a special */
/* function which abandons all the pending annotations */
/* specified up to that point within the current single */
/* alteration. Alternately, the programmer can commit */
/* the pending annotations and set them again in */
/* another alteration (overwriting the original */
/* annotations), or commit the pending annotations and */
/* call another function to purge them from the object. */
