Passing array of structures to function c++

Sorry for the noob question I'm just a little confused.
If I have an array of structures in main that I want to pass to a function:

struct MyStruct{
    int a;
    int b;
    char c;
    mayarray[5];
};  
MyStruct StructArray[10]; 

myFunction(StructArray[])

Pass to this to a function:

void myFunction(struct MyStruct PassedStruct[])
{
    PassedStruct[0].a = 1;
    PassedStruct[0].b = 2;
    // ... etc
}  

My question is, will calling the function like this modify the data in StructArray? I need it to. Would that be call by reference? I'm a little confused. How would I change it so that when I pass the array of structures to the function, the function will modify the array StructArray? I'musing visual studio btw.
Thanks.
