RE: [cdt-dev] org.eclipse.cdt.core.dom.parser.c
I found the problem. I deleted the first line, the include, I got 2 function names and 2 comments. So, one more question, I to resolve this one?
String[] includePaths = {"<stdio.h>"};// I know it should not be that 
IScannerInfo info = new ScannerInfo(definedSymbols, includePaths);
#include <stdio.h>
/*doc function1*/
int function1(int a){
 printf("This is function 1");
 return 0;
}
/*doc function2*/
int function2(char a){
printf("This is function 2");
return 0;
}
