I have a large body of code (2000+ lines at this point) with lots of global variables, and a handful of locals. I would like to know is there a way to print out all global variables in use at a particular moment in time either from the debugger (ideally) or in line?
Basically I have something like this for the menu
1. Do thing 1
2. Do thing 2
3. Do thing 3
4. Do thing 1 and 2
5. Do thing 1 and 3
6. Do thing 1, 2 and 3
The problem is, as you select something from the menu again after you finish an option, the globals are still set and I'd like to clear them. If I had a list of all of them, it be easy to copy and paste and set them before the program ran another entry again. Suggestions? I'm aware of reset [a-z], but all of my vars are uppercase, and I would upset INC, and other upper case built-ins.

View 3 Replies View RelatedI have a strange problem with a simple program. I have a container class that holds a pointer. I did this so I could use another container class that does several pass by value calls. I didn't want to be copying the object over and over again, so decided to build this simple container that simply copied the pointer in the copy constructor.
However, the pass by value call seems to be failing in a strange way. When the pass-by-value function is called, the program jumps into the copy constructor just fine and performs the pointer assignment operation. The program will copy the pointer value 0x20 (for argument sake) to the "this->base" location. Within the copy constructor, this has the address 0x28. Then when it jumps into the function, instead of pass by value argument being at 0x28 (as expected), it is at 0x36. Then 0x36->base has the address 0x28. Thus the base is now pointing at what was the new pointer container. At this point the data is corrupted and random things happen.
It seems that there is some strange assignment and double nesting going on. I really do not understand what is going on.
Below is some code. I have stripped away all the other code trying to isolate the problem. I have added comments explaining what my debugger is telling me.
Code:
using namespace std;
class paramPnt // Need to determine how order is tracked
{
private:
long order;

I hace some code C/C++ STL, which i need to use for android, using SDK-NDK-JNI.my problem is that i need to pass some STL structures across JNI, I can't pack/unpack data into basic types or arrays of basic types, doing my own simple streaming between the two layers.My application need to pass a pointer to a STL structure which is updated by eachuser interaction wonder if it is possible using NDK-JNI ?Other option is "native activity" but it also needs JNI in some way ... and passing the STL structures wille a requirement, yet.I only can package data into an own streaming if there is a second (concurrent) application running (implementing the STLfunctionality). Is it possible ?

I'm trying to pass a path as a string to an array, but its evaluating it as a command instead. I want to take the literal string "/mnt/accounts/user/temp/*.jpg" and assign it to an array{1}, but when i echo the array variable, it displays it as

pic2.jpg
pic3.jpg

I just want it to be the actual text "/mnt/accounts/user/temp/*.jpg" which i will be combining with other text to create a longer path elsewhere in the code.
I need to pass a large number of arguments to a function which takes variable number of arguments, such as gtk_list_store_new. But it doesn't look nice if i write something like gtk_list_store_new(NUM,TYPE_A,TYPE_B,TYPE_C,...,TYPE_OMEGA); because of large number of arguments. And, it will be a trouble to change number of columns because of need to manually change arguments to large number of such functions. So, how can i pass all the arguments to a function using a loop? Something like
Code:
for(i=0;i<NUM;i++)
{
push_arg(args[i]);
}
call_function(func);
?
Of course, i could just use asm code for this, but is there a portable way of doing so?
P.S. i mean C language.

I have some messy code that I wrote a while back and I am trying to organize it. The program opens xpaint and uses xwit and xte to draw packman and so on. I want to split it all up I am going to add more to it. Basically like i would want drawing packman in one function i guess you could call it and then coloring him or the background in another

Here for example $paintersmom is would be in the drawing of pacman but I would also want to use it when I colored him in.. but I would want both processes in a different shell script.

IS it possible to do what I need Without passing variables via the url? Page1 has all session variables set, calls the iframe command when users presses a button, Iframe loads but DOES not have the Session data that was saved on Page1 -- and IFRAME cannot pass variables via the URL it must be a direct url to the page only Page1.php java used to set the HTML / IFRAME into its Div

I'm running into a problem when I try to set a variable to an awk output in c-shell. Right now my command is Code: set STR_MSG_TYPE = `awk -F{ '/msg_type/ {print $2}' <filename> | tr -d }'/''*' ` I then run echo to see what the output is and it returns blank, however, when I run the same awk command from the command line, I get an actual output of "MT-715". Am I setting my variable incorrectly? I do something similar using the date command to set a STR_DATE variable earlier in the code and it works fine and I use the same syntax.

I have a C header file which have arrays of predefined(known) structure type. But i dont have names of arrays and their size. when i include that file and compile my application, i want to know the names and sizesof those arrays.
purpose of application is to get the content of those arrays and to explain it in descriptive words instead of hex numbers.ofcourse this can be done by file pointers and reading also with out header file inclusion, but as i am working in C, once compiled, those variables are in my address space in i include header file.

I am pretty new to PHP so excuse my dumbness. I've searched this up in quite a few places and cant find anything : Basically, I've made an array, within it are 3 more arrays. Their are two values in each array, 'Name' and 'Age'. Basically I am using a While statement to try and cycle through the 'age' value of my array and state whether or not the person is eligible. (I am actually just learning so I'm doing this to just test myself).
Here is my code
Code:
<?php
$people =array(
array('name' => 'Bob', 'age' => 15 ),
array('name' => 'Jhon' , 'age' => 10),
array('name' => 'Sue' , 'age' => 7));
//($value =& $people[0,1,2][age] );
Here was an attempt to try and create a reference to age, I tried it many different ways
while($age < 10) {
echo ('$name, is eligible') ; } ?>
Okay, so I tried to do this through two ways, one way I tried to create a reference to age, then evaluate it, without that line of code their would be no reference, which way is correct, why wont it work? I am using Xammp, so when I launch local host I get an undefined variable error. What To Do?
My php knowledge is very poor (only worked with strings so far), and I am faced which a task that is a real challenge for me: I have a variable, that contains data of different type, in this order: byte, byte, string, string, string, string, short, byte, byte, byte, byte, byte, byte, byte, string.
Strings are of variable length. How could this data be parsed into variables of the right type, and then all converted to strings? What are the functions to use? Strings are unicode ones, and they are delimited by "
