Objective-c syntax for passing a c-style array from NSStrings

What is the best syntax for passing a c-style array containing NSString*to an objective-c method? Here is what I am using now:

- (void) f:(NSString **) a {

}

- (void) g {
    NSString* a[2] = {@"something", @"else"};
    [self f:a];
}
