RE: [cdt-dev] org.eclipse.cdt.core.dom.parser.c
when I tested the c code with only one function(int function(int toto){int a;/*doc0*/
> > char b;/*doc1*/ return toto+a;}), I got doc0,doc1, with getComments(). with "for (IASTDeclaration declaration : translationUnit.getDeclarations()){
if( declaration instanceof IASTFunctionDefinition){
System.out.println(((IASTFunctionDefinition) declaration).getDeclarator().getName());
}" I got "function", so the function name in console. 

But when I tried a c file where I defined 2 functions. I got no function name. I think there would be something wrong in the code.
my CFile.c 
/*Documentation function1*/
int function1(char a){
printf("This is function1");
return 0;
}
/*Documentation function main*/
int main(void) {
puts("!!!Hello World!!!"); /* prints !!!Hello World!!! */
function1('1');
return EXIT_SUCCESS;
}
