You haven't called InitializeCriticalSection(&m_cs). Without
Hi,
Yes i use HeapCreate() and HeapAlloc().
I have a class object which is created on the heap and I have a member
variable in this class of type CRITICALSECTION (say m_cs). Inside one of my
class function when I call EnterCriticalSection(&m_cs) then this problem
occurs. Ok may be its not because of critical section because at the place
in code where EnterCriticalSection() was being called I create and
CAutoLock() object and pass my pointer to CRITICALSECTION object to it
(CAutoLock just call EnterCriticalSection in its constructor and
LeaveCriticalSection in its destructor). In the constructor when I try to
save pointer of critical section to the class member (CRITICALSECTION
*m_pCS) of CAutoLock then although it is pointer assignment but after
assignement the class member has some garbage data.
In my outside code:
{
CAutoLock(&m_cs);
// Some code
}
CAutoLock::CAutoLock(CRITICALSECTION *pCS)
{
m_pCS = pCS; <= This assignement is not working correctly and after
assignment m_pCS points to some garbage memory location
EnterCriticalSection(m_pCS);
}
So any idea what is wrong?
Thanks,

I have developed a static library which I am using in one of my
application.
In my library I have created my own heap and all the objects (class
objects)
in my application are created in that heap. What I have observed is that
in
my library at a certain place when I call EnterCriticalSection() to an
object allocated at my heap, it is corrupting my heap. I am using Windows
XP
and visual studio 8.0. Any hint how can I solve this problem?
How exactly do you create and use the heap?
Do you use HeapCreate/HeapAlloc/etc., or some other approach?
How do you detect the heap corruption?
How do you allocate memory for the CRITICAL_SECTION structure?
How do you pass this CRITICAL_SECTION to EnterCriticalSection?
Code samples would be helpful.
