// NewCallback converts a Go function to a function pointer conforming to the stdcall calling convention.
// This is useful when interoperating with Windows code requiring callbacks. The argument is expected to be a
// function with one uintptr-sized result. The function must not have arguments with size larger than the
// size of uintptr. Only a limited number of callbacks may be created in a single Go process, and any memory
// allocated for these callbacks is never released. Between NewCallback and NewCallbackCDecl, at least 1024
// callbacks can always be created. Although this function is similiar to the darwin version it may act
