in C++ "unhandled exception at 0x778215de in prject1.exe: 0xC0000005:Access violating writing location 0x00000016"

Question

When I am debugging a project, gives me an error on the window

unhandled exception at 0x778215de in prject1.exe: 0xC0000005:
Access violating writing location 0x00000016

And in mlock.c shows me that code lines:

void __cdecl _unlock (
        int locknum
        )
{
        /*
         * leave the critical section.
         */
        LeaveCriticalSection( _locktable[locknum].lock );
}

How can I solve this problem?

Looks like you are accessing your array out of its bounds... You should check if your array contains more than 22 items.

OR

You should check if the item is properly initialized at position 22.

Thx for ur answer, but how to undestand an array contains more that 22? And why 22? And my arrays haven't overloading. Have u any idea? – 11532 Apr 11 '13 at 07:33
You are trying to write to a location `0x16`, which is 22 in decimal system. Anyway you are writing to an index in your array that is not properly initialized. – bash.d Apr 11 '13 at 07:35
Yes, of course. The program gives me like this error: [link](http://img42.imageshack.us/img42/2428/1a68456c64bf2b02219b5f1.jpg) – 11532 Apr 11 '13 at 10:12
What is `_locktable[]` by the way? How is it defined? – bash.d Apr 11 '13 at 11:13
I don't know. I beginner of that sphere. – 11532 Apr 11 '13 at 11:18
The mlock.c file is automatically created. And It said that is "Multi-thread locking routines" – 11532 Apr 11 '13 at 11:49
Is this project available online? Sounds like tough stuff, multi-threading is quite difficult. – bash.d Apr 11 '13 at 12:06
No, it isn't available online. it's written by myself. I wrote that code from a book – 11532 Apr 11 '13 at 12:23
Sorry, but if you have no serious clue what you are doing, it is hard to help you... – bash.d Apr 11 '13 at 12:27
I generally understood meaning of the code. But I can't understand, which that code from a book, so why it's invalid – 11532 Apr 11 '13 at 12:31
then please post all of your code or link it to pastebin or anything – bash.d Apr 11 '13 at 12:33
I'm converting all comments from my language to english. It's take over 30-40 minuts – 11532 Apr 11 '13 at 12:48
Do u have a mail to send files? – 11532 Apr 11 '13 at 14:18
I have more SLOC. I have two files: a header and a cpp files. – 11532 Apr 11 '13 at 14:21
