Why

getnameinfo

function for macosX64 and linuxX64 target in

platform.posix

but for mingwX64 in

platform.windows

? It it a bug or feature?

This is an expectable difference, as this function is located in different headers:

ws2tcpip.h

for mingw_x64 target and

netdb.h

for macOS/Linux. The first header is defined as a part of

windows.def

, while the second can be found in

<osx|linux>/posix.def

. While it can be relocated to the mingw’s posix KLIB, one could say it is controversial decision.

I use “host” target - same as https://github.com/Kotlin/kotlinconf-spinner/tree/master/httpserver And I’ve added

getnameinfo

function to allow requests only from localhost. And now I can’t compile same code on Win and Mac. How can I do it? I can’t use 1.4-M3 because my app cann’t be compiled on this version.

Hmm, that could be a problem. Maybe this obstacle worth moving to more straightforward targeting, with separate source sets. If the signature is the same, one could try using expect/actual mechanism, typealiasing actual function to a platform-specific one.

expect typealias Addr

Modifier 'expect' is not applicable to 'typealias'

Sorry, I meant something like

expect fun getAddr

in the common code, with appropriate signature, and

actual typealias getAddr = platform.posix.getaddrinfo

expect fun getAddr(addr: CPointer<sockaddr>?)

- type

CPointer<sockaddr>?

isn’t allowed in common code Now I’ve created

expect fun getNameInfo(addrAsLong: Long, addrLength: UInt): String

and

if (getIdAddr(addr.toLong(), addrLen) == LOCALHOST) {
    MHD_YES
} else {
    MHD_NO
}

but it looks like ugly
