Cast is used to centralize unsafe use C of allocated pointer.

CastWithOffset is the same as cast but adding an offset to the pointer by a multiple of the size of the type pointed.

Cstring converts a go string to *byte that can be passed to C code.

Gostring copies a char* to a Go string.

KeepAlive is a copy of runtime.KeepAlive keepAlive has 2 usages: - It forces the deallocation of the memory to take place later than expected (just like runtime.KeepAlive) - It forces the given argument x to be escaped on the heap by saving it into a global value (Go doesn't provide a standard way to do it as of today) It is implemented so that the compiler cannot optimize it.

NativeStringUnwrap cast a native string type into it's runtime value.

NativeToUintptr is a helper used by populate WafObject values with Go values.

PtrToUintptr is a helper to centralize of usage of unsafe.Pointer do not use this function to cast interfaces.

UintToNative is a helper used retrieve Go values from an uintptr encoded value from a WafObject.
