Detailed Description

The class provides a fast way of allocating memory in certain limits.

The class allocates a large chunk of memory in the constructor then it uses a stack based allocator. Both allocating and freeing is very fast provided that the limit was not reached.

For requests that are larger than the buffer standard malloc is used.

Member Function Documentation

bool bbb::DynStack::isEmpty ( void  )

inline

tell if the instance is empty or not

This will only check the stack, not dynamic blocks.

bool DynStack::reinit

(

int

sz

)

reinitialise with a different size

This is only allowed if the stack is empty

void DynStack::reset

(

void

)

sets the top of the stack to 0

All the memory that was allocaed is asserted that was freed at this time
