Thread: Mutex across multiple source files

It's more complicated that that. I simplified the example...

I'm passing this structure:

Code:

typedef struct {        /* Country mutex structure */
        pthread_mutex_t resA, resE, resP, resM;
        pthread_mutex_t purchase1, purchase2;
} CountryMutex;

Into this function:

Code:

 
void findDeficit(const Config *config, const CountryStruct *country, CountryDeficit *cdeficit, CountryMutex *cmutex) {
pthread_mutex_lock(&cmutex->resA);
...
pthread_mutex_unlock(&cmutex->resA);
}

Using this call:

Code:

CountryMutex cmutex;
pthread_mutex_init(&cmutex.resA, NULL);
pthread_mutex_init(&cmutex.resE, NULL);
pthread_mutex_init(&cmutex.resP, NULL);
pthread_mutex_init(&cmutex.resM, NULL);

findDeficit(config, country, cdeficit, &cmutex);   << EDIT

Shouldn't this work? Passing a pointer to a structure of mutexes?
