We have a module which makes use of ioctl_socket() function, I have included #include <sys/ioctl.h> in the .cpp but still throws the below error :

'ioctl_socket' was not declared in this scope
             if (ioctl_socket( sockFd, SIOCSETVLAN, &ifr) == -1)
                 ^~~~~~~~~~~~

Any suggestions on how to fix the compilation error? thanks in advance.
