我正在尝试调用函数DSPSplitComplex：

var real = [Float](input_windowed)
var imaginary = [Float](repeating: 0.0, count: input_windowed.count)
        
var splitComplex = DSPSplitComplex(realp: &real, imagp: &imaginary)

但这会给我们一个警告

Cannot use inout expression here; argument 'realp' must be a pointer that outlives the call to 'init(realp:imagp:)'

所以在那之后我试着

var splitComplex = DSPSplitComplex(
    realp:  UnsafeMutablePointer(mutating: real),
    imagp:  UnsafeMutablePointer(mutating: imaginary) )

这就给出了警告：

Initialization of 'UnsafeMutablePointer<Float>' results in a dangling pointer

所以最后我试了这个：

var splitComplex =
    withUnsafeMutablePointer(to: &real) { realpPtr in
        withUnsafeMutablePointer(to: &imaginary) { imaginaryPtr in
            DSPSplitComplex(realp: realpPtr, imagp: imaginaryPtr)
    }
}

并且 that 会产生以下编译错误：

Cannot convert value of type 'UnsafeMutablePointer<[Float]>' to expected argument type 'UnsafeMutablePointer<Float>'

调用此函数（以及Accelerate框架中的类似函数）的正确方法是什么？
