Hi,
I’ve narrowed down the issue a bit more.
The problem is when I have
Foo::update(const char * str, MyObj *obj){ g_hash_table_insert(table, (char*)str, obj);
}
and I’m calling it with
update(someobj->toString().c_str(), obj); update(someobj2->toString().c_str(), obj2);
When I try to insert multiple objects of c_str(), then
Is there anyway I can store in / GHashTable takes in strings as *string literals* ? The issue I come across when after I insert two of these types of objects, and I run g_hash_table_foreach(), then the loop keeps on repeating itself infinitely, I believe because of something due to using c_str() as the key.
Thanks.

Hi,
Lets say I have my table
Class Foo{ GHashTable *table; }
foo::foo(){ table = g_hash_table_new(g_str_hash, g_str_equal); }
I have functions like
Foo::update(Address *addr, MyObj *obj){ g_hash_table_insert(table, (char*)addr->toString().c_str(), obj);
}
and in another function
Foo::dostuff(){
update(addr1, obj1); update(addr2, obj2);
}
Each time I call update, it changes the hash table so that lets say addr1->toString().c_str() gave “helloaddress” first, the second time I call it, where it becomes “byebyeaddress” (addr2….), the items in the hash table change.
It seems like the hash table just copies pointers – is that true? If so, how else can I modify this so I can store the correct key and values, without concern that the keys and values will change outside of modifying the hash table?
Thanks.
