Untyped Allocation API.
Defines the 'C-style' part of the API, where memory management is fully untyped (i.e. done with void pointers and explicit size values). This API should usually not be used anymore in C++ code, unless some form of raw memory management is necessary (e.g. for allocation of various ID types based on their IDTypeInfo::struct_size data).

Allocate a block of memory of size (len * size), with tag name str, aborting in case of integer overflows to prevent vulnerabilities. The memory is cleared. The name must be static, because only a pointer to it is stored!

References ATTR_WARN_UNUSED_RESULT, len, MEM_calloc_arrayN(), size(), and str.

◆ MEM_callocN()

void * MEM_callocN	(	size_t	len,

References len, mem_guarded::internal::mem_callocN, and str.

◆ MEM_dupallocN()

void * MEM_dupallocN ( const void * vmemh )

Duplicates a block of memory, and returns a pointer to the newly allocated block. NULL-safe; will return NULL when receiving a NULL pointer.

References mem_guarded::internal::mem_dupallocN.

◆ MEM_enable_fail_on_memleak()

void MEM_enable_fail_on_memleak ( void )

When this has been called and memory leaks have been detected, the process will have an exit code that indicates failure. This can be used for when checking for memory leaks with automated tests.

Definition at line 82 of file leak_detector.cc.

Referenced by arg_handle_debug_exit_on_error().

◆ MEM_freeN()

void MEM_freeN ( void * vmemh )

Release memory previously allocated by the C-style functions of this module.

It is illegal to call this function with data allocated by #MEM_new.

Definition at line 113 of file mallocn.cc.

References mem_guarded::internal::ALLOC_FREE, and mem_guarded::internal::mem_freeN_ex.

◆ MEM_init_memleak_detection()

void MEM_init_memleak_detection ( void )

This should be called as early as possible in the program. When it has been called, information about memory leaks will be printed on exit.

This variable is constructed when this function is first called. This should happen as soon as possible when the program starts.

It is destructed when the program exits. During destruction, it will print information about leaked memory blocks. Static variables are destructed in reversed order of their construction. Therefore, all static variables that own memory have to be constructed after this function has been called.

◆ MEM_use_guarded_allocator()

void MEM_use_guarded_allocator ( void )

Switch allocator to slow fully guarded mode.

Use for debug purposes. This allocator contains lock section around every allocator call, which makes it slow. What is gained with this is the ability to have list of allocated blocks (in an addition to the tracking of number of allocations and amount of allocated bytes).

Note: The switch between allocator types can only happen before any allocation did happen.

◆ MEM_use_lockfree_allocator()

void MEM_use_lockfree_allocator ( void )

Switch allocator to fast mode, with less tracking.

Use in the production code where performance is the priority, and exact details about allocation is not. This allocator keeps track of number of allocation and amount of allocated bytes, but it does not track of names of allocated blocks.
