"Initializing" the pointer in the separate function in C
- by pechenie
I need to do a simple thing, which I used to do many times in Java, but I'm stuck in C (pure C, not C++). The situation looks like this:
int *a;
void initArray( int *arr )
{
arr = malloc( sizeof( int ) * SIZE );
}
int main()
{
initArray( a );
// a is NULL here! what to do?!
return 0;
}
I have some "initializing" function, which SHOULD assign a given pointer to some allocated data (doesn't matter). How should I give a pointer to a function in order to this pointer will be modified, and then can be used further in the code (after that function call returns)?
Thanx for help.
