RE: [cdt-dev] org.eclipse.cdt.core.dom.parser.c
andreas, I tried that :
String[] includePaths = {"C:\\MinGW\\include","C:\\MinGW\\lib\\gcc\\mingw32\\3.4.5\\include"};
I got 2 IASTComments, 0 Declarations.

As a quick guess, I'd say that includePaths should probably an array of directories, not <....> strings.

This is the c source file that i test in my example:
#include <stdio.h>
#include <stdlib.h>
/* Documentation function 1*/
int function1(int a){
 printf("This is function 1");
 return 0;
}

/*Documentation function 2*/
int function2(char a){
printf("This is function 2");
return 0;
}
This is my example:
IParserLogService log = new DefaultLogService();
String codeString = "";
/*******   Take a c source file  ********/
File file = new File("Y:\\IFX_Tools\\Plugin_Eclipse\\workspace\\ParserCDT\\src\\CFile.c");
    FileInputStream fis = null;
    BufferedInputStream bis = null;
    DataInputStream dis = null;

    try {
      fis = new FileInputStream(file);

      bis = new BufferedInputStream(fis);
      dis = new DataInputStream(bis);

      while (dis.available() != 0) {
     codeString = codeString.concat(dis.readLine());
        //System.out.println(dis.readLine());
      }
      fis.close();
      bis.close();
      dis.close();

    } catch (FileNotFoundException e) {
      e.printStackTrace();
    } catch (IOException e) {
      e.printStackTrace();
    }

char[] code = codeString.toCharArray();
CodeReader reader = new CodeReader(code);
Map definedSymbols = new HashMap();
String[] includePaths = {"<stdio.h>"};
IScannerInfo info = new ScannerInfo(definedSymbols, includePaths);
ICodeReaderFactory readerFactory = FileCodeReaderFactory.getInstance();
IASTTranslationUnit translationUnit = GCCLanguage.getDefault().getASTTranslationUnit(reader, info, readerFactory, null, log); 
// Function name
for (IASTDeclaration declaration : translationUnit.getDeclarations()){
if( declaration instanceof IASTFunctionDefinition){
System.out.println(((IASTFunctionDefinition) declaration).getDeclarator().getName());
}
}
// comments
for (IASTComment com :translationUnit.getComments()){
System.out.println(com.toString());
}

I got the  result and that's correct:
function1
function2
/*doc function1*/
/*doc function2*/

But when I add some inclusions in my c file: 
#include <stdio.h>
#include <stdlib.h>
I get nothing in console.
I want to know,  should I do something like:
String[] includePaths = {"<stdio.h>"};// I know it should not be that
 IScannerInfo info = new ScannerInfo(definedSymbols, includePaths);

Isn't it ? If not, how should i do? 
Thanks a lot
