How can I use structs? about cordova-plugin-hello-c HOT 2 CLOSED

This example plugin only demonstrates primitive types such as int and string.
I'm unsure if the Android JNI supports passing of complex types but that is beyond the scope of this simple example.
For iOS it's easier as you only have to map the stringified Javascript structure passed via the Cordova plugin interface to C types in your Objective C plugin implementation.
I'd suggest Googling how to pass complex types using the Android JNI as this is not something I've had need to do so have no experience with.

Android is over for this project. iOS is the main.

My problem is when Objective try to read a Struct from JS.

- (void) calc_example:(CDVInvokedUrlCommand *)command
{

    // option 1 - NSString* a = [[command arguments] objectAtIndex:0];
    // option 2 - NSArray* a = [[command arguments] objectAtIndex:0];
    // option 3 - NSDictionary* a = [[command arguments] objectAtIndex:0];
    // More options?

    float output = calc_example(a);
    
    CDVPluginResult* result = [CDVPluginResult
                               resultWithStatus:CDVCommandStatus_OK
                               messageAsDouble:output];

    
    [self.commandDelegate sendPluginResult:result callbackId:command.callbackId];
}
