Detailed Description

Allocated memory blocks can be made invisible: They won't show up in the overview of allocated memory anymore. Even more, the corresponding alloc_ct is destroyed: find_alloc will not find them anymore. There is no other effect, test_delete will still work and they still can be deleted in the normal way.

Function Documentation

◆ make_all_allocations_invisible_except()

void libcwd::make_all_allocations_invisible_except ( void const * ptr )

inline

Make all current allocations invisible except the given pointer.

All allocations, except the given pointer, are made invisible; they won't show up anymore in the overview of allocated memory.

If you want to make all allocations invisible, just pass NULL as parameter.

Example:

Debug( make_all_allocations_invisible_except(NULL) );

Debug

#define Debug(STATEMENTS...)

Encapsulation macro for general debugging code.

Definition: debug.h:124

libcwd::make_all_allocations_invisible_except

void make_all_allocations_invisible_except(void const *ptr)

Make all current allocations invisible except the given pointer.

Definition: debugmalloc.cc:3219

◆ make_exit_function_list_invisible()

void libcwd::make_exit_function_list_invisible ( )

Make allocations done in libc.so:__new_exitfn invisible.

This makes the allocation done in __new_exitfn (libc.so) invisible because it is not freed until after all __cxa_atexit functions have been called and would therefore always falsely trigger a memory leak detection. This function can be called first thing in main().
