Releases unused heap memory to the operating system. Syntax C int_heapmin(void); Return value If successful,_heapminreturns 0; otherwise, the function returns -1 and setserrnotoENOSYS. For more information about this and other return codes, seeerrno,_doserrno,_sys_errlist, and_sys_nerr. ...
//en.wikipedia.org/wiki/B-heap. Heap pages containing more than one page chunk can be useful if multiple item accesses inside heap page is faster than multiple accesses to items across distinct heap pages. This can be the case for systems with virtual memory, where VM pages can be swapped...

userData Pointer to the beginning of an allocated memory block. Return Value: _CrtIsValidHeapPointer returns TRUE if the specified pointer is in the local heap. Otherwise, the function returns FALSE. 也就是说仅在debug版本中检查free参数是否为the beginning of an allocated memroy block. ...
Another common problem faced by many Unity developers is the unexpected expansion of the managed heap. In Unity, the managed heap expands much more readily than it shrinks. Furthermore, Unity’s garbage collection strategy tends to fragment memory, which
