While not part of OWL, the "Borland WinSys Library" does define
registry classes (\include\winsys\registry.h). Look at winsys.hlp.

You can do stuff like this:

    char buff[256];
    char value[512];
    uint32 size, type;
    TRegKey my_key(TRegKey::GetClassesRoot(), "MyClass\\MyKey");
    size = sizeof(value);
    type = REG_SZ;
    memset(buff, 0, sizeof(buff));
    int index = 0;
    while (my_key.EnumKey(index, buff, sizeof(buff)) ==
ERROR_SUCCESS){
        index++;
        TRegKey key(my_key, buff);
        value[0] = 0;
        size = sizeof(value);
        if (key.QueryValue("VALUE1", &type, (uint8*)value, &size) ==
ERROR_SUCCESS){
            strcpy(value, "another value");
            size = lstrlen(value);
            type = REG_SZ;
            key.SetValue("VALUE2", type, (uint8*)value, size);
        }
    }

HTH,
