Hi Experts,
Is it possible to declare multiple static variables of same name in a single C file with different scopes?
I wrote a simple programme to check this and in gcc it got compiled and worked fine.
code:
static int sVar = 44;
void myPrint2()
{
printf("sVar = %d\n", sVar++);
}
void myPrint()
{
static int sVar =88;
p...
I'm very new to servlets. I'd like to serve some static files, some css and some javascript. Here's what I got so far:
In web.xml:
<servlet>
<description></description>
<display-name>StaticServlet</display-name>
<servlet-name>StaticServlet</servlet-name>
<servlet-class>StaticServlet</servlet-class>
</servlet>

I am trying to change the value of a "static char *" I define at startup, I do it from inside a function, and when this function returns the var I am trying to re-set the value doesn't retain it.
Example:
static char *X = "test_1";
void testFunc()
{
char buf[256];
// fill buf with stuff...
X = buf;
}
How can I achieve th...
I've been reading up on C++ on the Internet, and here's one thing that I haven't been quite able to find an answer to.
I know that static variables used within functions are akin to globals, and that subsequent invocations of that function will have the static variable retain its value between calls.
However, if the function is never c...
I'm curious about the following code:
class MyClass
{
public:
MyClass() : _myArray(new int[1024]) {}
~MyClass() {delete [] _myArray;}
private:
int * _myArray;
};
// This function may be called by different threads in an unsynchronized manner
void MyFunction()
{
static const MyClass _myClassObject;
[...]
}
Is there a p...
My program has a static list of type classA. ClassA implements a threading timer that executes a task. The list may contain as many instances of classA as desired. Is this technique causing threading issues where the class instances can block each other? It that is the case how can I solve the that problem. ex:
static List<MyClassType> ...
I was looking over some code the other day and I came across:
static {

}
Coming from C++, I had no idea why that was there. Its not an error because the code compiled fine. What is this "static" block of code?

In objective-c, I have a utility class with a bunch of static methods that I call for various tasks. As an example, I have one method that returns an NSArray that I allocate in the static method. If I set the NSArray to autorelease, then some time later, the NSArray in my calling method (that is assigned to the returned pointer) losses...
I have a C project that produces ten executables, all of which I would like to be linked in statically. The problem I am facing is that one of these executables uses a 3rd-party library of which only the shared-object version is available.
If I pass the -static flag to gcc, ld will error saying it can't find the library in question (I p...
With Struts2 I can't find a way to serve a static CSS :-/ Newbie question but I could not find any answer on the Internet:
The CSS file is static/styles.css in my WAR file.
Tomcat replies with 404 when I request http://server/myapp/static/styles.css
But it works if I put styles.css at the root of the WAR and request http://server/myap...
Hello,
I am new to Python and this is my first time asking a stackOverflow question, but a long time reader. I am working on a simple card based game but am having trouble managing instances of my Hand class. If you look below you can see that the hand class is a simple container for cards(which are just int values) and each Player c...
When would a singleton actually be easier or better than a static class? It seems to me creating a singleton is just extra effort that's not actually needed, but I'm sure there is a good reason. Otherwise, they wouldn't be used, obviously.

I wonder about the use of the static keyword as scope limiting for variables in a file, in C.
The standard way to build a C program as I see it is to:
have a bunch of c files defining functions and variables, possibly scope limited with static.
have a bunch of h files declaring the functions and possibly variables of the corresponding...

I have a class containing, among other things, a drop down menu. With the aim of saving space, and since the contents of the menu will never change, I've made a static DataProvider for the whole class that populates each instances menu. I was hoping to populate the list with actual functions like so:
tmpArr.push({label:"Details...", fu...
Hi all -
I have the following static function:
static inline HandVal
StdDeck_StdRules_EVAL_N( StdDeck_CardMask cards, int n_cards )
Can I export this function in a DLL? If so, how?
Thanks,

How do I access a static member in a class with all static methods?
I want to have a group of related functions but also have some important data members initialized before any of these functions are called. I thought a class with only static members would be the way to go. Compiler in VS2008 doesn't like me trying to access "a".

If I have a bunch of data that is never going to change (eg. an English language dictionary or the rgb values of a couple hundred color names), how do I use an SQLite database to store it? I know a database is faster than loading everything into memory when the app starts, but how do I make the database either the first time the app runs...
