buildJavaVMInitArgs

context(placement: NativePlacement)
inline fun buildJavaVMInitArgs(version: JniVersion, optionsCount: Int, ignoreUnrecognized: Boolean = false, block: JavaVMInitArgsBuilder.() -> Unit): JavaVMInitArgs(source)

Allocates and initializes JavaVMInitArgs.

Instead of writing

val options = allocArray<JavaVMOption>(4)
var i = 0
options[i++].option = "-Djava.compiler=NONE"                // disable JIT
options[i++].option = "-Djava.class.path=C:\\myclasses"     // user classes
options[i++].option = "-Djava.library.path=C:\\mylibs"      // set native library path
options[i++].option = "-verbose:jni"                        // print JNI-related messages

val args = alloc<JavaVMInitArgsStruct>()
args.version = JNI.v21
args.ignoreUnrecognized = false.toJBoolean()
args.nOptions = i
args.options = options

You may write

val args = buildJavaVMInitArgs(JNI.v21, 4) {
    option("-Djava.compiler=NONE")               // disable JIT
    option("-Djava.class.path=C:\\myclasses")    // user classes
    option("-Djava.library.path=C:\\mylibs")     // set native library path
    option("-verbose:jni")                       // print JNI-related messages
}

Which will be inlined in the code above.
