Detailed Description

Global ANSI Memory Manager helper class.

---

This class is a helper that attaches a MemoryManagerANSI class to the global memory manager. When this instance shuts down, it will remove itself from the global memory manager and set the global memory manager to the previous one.

MemoryManagerGlobalANSI() [3/3]

Burger::MemoryManagerGlobalANSI::MemoryManagerGlobalANSI ( )

noexcept

Attaches a MemoryManagerANSI class to the global memory manager.

---

When this class is created, it will automatically attach itself to the global memory manager and save the pointer to the previous instantiation so when this class goes out of scope, the previous memory manager is reinstated

Example...

void DoSomething()
{
 // Tell Burgerlib to use ANSI memory chunks
 MemoryManagerGlobalANSI MallocMemory;
 CallFunctionThatUsesMemory();
 CallFunctionThatCleansUpMemory();
 // When going out of scope, HandleBasedMemory is restored
}
 
int main(int,char **)
{
 // Use handle based memory
 Burger::MemoryManagerGlobalHandle HandleBasedMemory;
 DoSomething();
 return 0;
}

~MemoryManagerGlobalANSI()

Burger::MemoryManagerGlobalANSI::~MemoryManagerGlobalANSI

(

)

Releases a MemoryManagerANSI class from the global memory manager.

---

When this class is released, it will automatically remove itself to the global memory manager and restore the previous memory manager to the global memory manager.
