Method MemoryUtil.FreeAlloc

---

Overload

Frees a memory block (if not null) and allocates new.

public static void FreeAlloc<T>(ref T* mem, nint count, bool zeroInit = false) where T : unmanaged

Parameters

mem  (T*) Input: old memory address or null. Output: new memory address; null if exception (it prevents freeing twice).

count  (nint) New count of elements of type T.

zeroInit  (bool) Set all bytes = 0.

Exceptions

OutOfMemoryException Failed. Probably count is too big.

Type Parameters

T

Remarks

At first sets mem = null, to avoid double Free if this function throws exception. Then calls Free and Alloc.
