|
| void | fiftyoneDegreesSetUpMemoryTracking ()
Setup memory tracking by resetting memory tracking and setting all Malloc/Free function pointers to pointer to TrackingMalloc/Free functions.
|
| size_t | fiftyoneDegreesUnsetMemoryTracking ()
This function works in collaboration with fiftyoneDegreesSetUpMemoryTracking. More...
|
| EXTERNAL_VAR void *(* | fiftyoneDegreesMalloc )(size_t __size)
Pointer to the method used to allocate memory. More...
|
| EXTERNAL_VAR void *(* | fiftyoneDegreesMallocAligned )(int alignment, size_t __size)

|
| EXTERNAL_VAR void(* | fiftyoneDegreesFree )(void *__ptr)
Pointer to the method used to free memory. More...
|
| EXTERNAL_VAR void(* | fiftyoneDegreesFreeAligned )(void *__ptr)

|
| bool fiftyoneDegreesMemoryAdvance | ( | fiftyoneDegreesMemoryReader * | reader, |
| size_t | advanceBy | ||
| ) |
Used to read continuous memory checking for buffer over or under runs.
| void fiftyoneDegreesMemoryStandardFree | ( | void * | __ptr | ) |
Frees memory using the standard free method.
| void fiftyoneDegreesMemoryStandardFreeAligned | ( | void * | __ptr | ) |
Frees memory using the standard aligned free method.
| void* fiftyoneDegreesMemoryStandardMalloc | ( | size_t | __size | ) |
Allocates memory using the standard malloc method.
| void* fiftyoneDegreesMemoryStandardMallocAligned | ( | int | alignment, |
| size_t | __size | ||
| ) |
Allocated aligned memory using the standard malloc method.
| void fiftyoneDegreesMemoryTrackingFree | ( | void * | __ptr | ) |
Frees memory allocated using the fiftyoneDegreesMemoryTrackingMalloc method, noting that it has now been freed and does not contribute to the current total.
| void fiftyoneDegreesMemoryTrackingFreeAligned | ( | void * | __ptr | ) |
Frees memory allocated using the fiftyoneDegreesMemoryTrackingMallocAligned method, noting that it has now been freed and does not contribute to the current total.
| size_t fiftyoneDegreesMemoryTrackingGetAllocated | ( | ) |
Gets the current number of bytes allocated using the tracking malloc and free methods.
| size_t fiftyoneDegreesMemoryTrackingGetMax | ( | ) |
Gets the maximum total number of bytes that have been allocated using the fiftyoneDegreesMemoryTrackingMalloc method.
NOTE: this is the total at any point in time since the fiftyoneDegreesMemoryTrackingReset method was called, NOT the total allocated in a single allocation.
| void* fiftyoneDegreesMemoryTrackingMalloc | ( | size_t | __size | ) |
Allocates memory while keeping track of the memory which has been allocated using this method since calling fiftyoneDegreesMemoryTrackingReset.
| void* fiftyoneDegreesMemoryTrackingMallocAligned | ( | int | alignment, |
| size_t | __size | ||
| ) |
Allocates aligned memory while keeping track of the memory which has been allocated using this method since calling fiftyoneDegreesMemoryTrackingReset.
| void fiftyoneDegreesMemoryTrackingReset | ( | ) |
Resets the memory trackers keeping track of the data allocated using the fiftyoneDegreesMemoryTrackingMalloc method.
This should always be called before tracking memory allocations.
| size_t fiftyoneDegreesUnsetMemoryTracking | ( | ) |
This function works in collaboration with fiftyoneDegreesSetUpMemoryTracking.
Check if all tracking memory has been freed. Unset memory tracking by setting all Malloc/Free function pointer to standard Malloc/Free functions. Then, reset memory tracking.
| EXTERNAL_VAR void( * fiftyoneDegreesFree) (void *__ptr) |
Pointer to the method used to free memory.
By default this maps to fiftyoneDegreesMemoryStandardFree which calls the standard library free.
| EXTERNAL_VAR void( * fiftyoneDegreesFreeAligned) (void *__ptr) |
Pointer to the method used to free memory.
By default this maps to fiftyoneDegreesMemoryStandardFreeAligned which calls the standard library free.
| EXTERNAL_VAR void*( * fiftyoneDegreesMalloc) (size_t __size) |
Pointer to the method used to allocate memory.
By default this maps to fiftyoneDegreesMemoryStandardMalloc which calls the standard library malloc.
| EXTERNAL_VAR void*( * fiftyoneDegreesMallocAligned) (int alignment, size_t __size) |
Pointer to the method used to allocate aligned memory.
By default this maps to fiftyoneDegreesMemoryStandardMallocAligned which calls the standard library malloc, allocating slightly more that requested, then ensures the pointer is aligned to a boundary.
