how to correctly call the function:

@kotlinx.cinterop.internal.CCall public external fun SCNetworkReachabilityGetFlags(target: platform.SystemConfiguration.SCNetworkReachabilityRef? /* = kotlinx.cinterop.CPointer<cnames.structs.__SCNetworkReachability>? */, flags: kotlinx.cinterop.CValuesRef<platform.SystemConfiguration.SCNetworkReachabilityFlagsVar /* = kotlinx.cinterop.UIntVarOf<kotlin.UInt> */>?): kotlin.Boolean { /* compiled code */ }

to receive the kSCNetworkReachabilityFlags… correctly?

in Swift, we can make the call:

var flags: SCNetworkReachabilityFlags = []
if !SCNetworkReachabilityGetFlags(defaultRouteReachability, &flags) {
    return false
}

And receive the flags in an array style….

In Kotlin Native, I am doing:

// val flags = allocArray<SCNetworkReachabilityFlagsVar>(10) // -> this was my first attempt, they are 10 possible flags!
val flags = alloc<SCNetworkReachabilityFlagsVar>()

if (!SCNetworkReachabilityGetFlags(reachabilityRef, flags.ptr)) return false

the problem is I am receiving all the flag “summed” (they are kotlin.UInt), and not split in an array, like in Swift.

Try allocArrayOf()

@russhwolf the allocArrayOf() needs a vargarg as a parameter, how could I use it?

Hello, @magnumrocha! I’ve found an example here, thanks to the thread. Please take a look.

thanks @Artyom Degtyarev [JB] 👍 I’m using it right this way
