That's right Helko. 

I also need all function names, I tried to do: 

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());

      }

      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 = new String[0];//{"#include <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 only the comments this time. No declarations, what's wrong?

CFile.c

#include <stdio.h>

#include <stdlib.h>

/* Documentation function 1*/

int function1(int a){

 printf("This is function 1");

 return 0;

}

/*Documentation function main*/

int main(void) {

puts("!!!Hello World!!!"); /* prints !!!Hello World!!! */

function1(0);

return EXIT_SUCCESS;

}
