I am interfacing with libxml2 in swift, and the C APIs binding (still) produce UnsafePointer<Int8>! for c-strings. Whereas Swift APIs normally result in UnsafePointer<UInt8>!.
So my question is - am I doing the string to null-terminated C-string conversion correctly?
let cfilePath = unsafeBitCast(myStringString.nulTerminatedUTF8.withUnsafeBufferPointer { $0.baseAddress }, to: UnsafeMutablePointer<Int8>.self)
Should I instead prefer using some other method instead of just bypassing Swift type checking with interpreting UInt8 bytes as Int8 bytes?
