Kotlin/Native newbie question… I’m trying to work with a library that defines all string parameters as unsigned char *. How do I take a Kotlin string and convert it to that? (cinterop has given the parameter the type CValuesRef<UByteVar>, which means I can’t just use .cstr or .wcstr)

Header file is https://github.com/yaml/libyaml/blob/master/include/yaml.h, function I’m looking at in particular is yaml_parser_set_input_string

You'll need to use, memScoped and cstr.getPointer(memScope).reinterpret<UByteVar>()

Thanks!

Also be aware that the string passed in will only live as long as the memScoped block.

The line cstr.getPointer(memScope).reinterpret<UByteVar>() can be replaced with cstr.ptr.reinterpret<UByteVar>(), provided cstr is allocated in the memScoped block.

Perfect, thanks
