19.2. Contrôle de la partie module
Chaque module peut-être contrôlé d'une manière similaire, vous trouverez ci dessous un simple
programme d'exemple affichant les principaux paramètres d'un module et permettant d'activer la
balise de localisation.
#import <Foundation/Foundation.h>
#import "yocto_api.h"
static void usage(const char
{
NSLog(@"usage: %s <serial or logical name>
exit(1);
}

{
NSError *error;
@autoreleasepool {
// Setup the API to use local USB devices
if([YAPI RegisterHub:@"usb": &error] != YAPI_SUCCESS) {
