Hi all,

 I know that the function CeRapiInitEx returns immediately. No wait for processing.

 I want to implement such a function. Returns immediate. no wait.

 How do I implement such a function?


Thanks

4. function doesn't return simply skip the return line

Hello to all, i have the following functions:

string File::readLine(){
	char ch;
	string str;
	ch = read();
	while(ch != LF && ch != CR && ch != -1){
		str.append(1,ch);
		ch = read();
	}
	if(ch == -1){
		cout << "this line could not be read" << endl;
		exit(1);
	}
	//take care of situation where the loop exited with LF but
	//on a system that has CR.
	int tmp = file->tellg();
	if(read() != CR){ //if no CR available on system, return the get
pointer to it's correct location.
		file->seekg(tmp);
	}
	return str;
}

the function is executed correctly but in the end it skips the "return
str" line,
and tun flies with an error.
debugging took me to a qt class moc_myclass.cpp (it's a qt project in
eclipse)
to a line where it says "_id -= 1;"
inside a function called "int myclass::qt_metacall(...)"

can anyone help me??????????

5. return type of a function that returns a local variable

6. Forgetting to write a return in a function returning a value

Why doesn't my compiler (g++) flag something like this as an error:

int main()
{
}

?

8. Want to create a function which returns a value obtained from a callback function

Hello

I want to write a C++ function which returns a Windows handle.  I need
to call a callback function to find the Window.  The specific function
is EnumChildWindows.

As the final parameter of EnumChildWindows I can pass a pointer back
to my class.  so I can access class functions ok.  I thought that I
could have a member variable in the class which is an HWND.  Then the
this variable could be updated by EnumChildWindows if a window handle
is found.  then when the function returns I just take the value in the
variable as the first found windows handle.

I suppose that would work but it doesn't feel so elegant.  Has anyone
got any better ideas?
