NF_STATUS nf_registerDriver(const char * driverName)
NF_STATUS_SUCCESS on success, or other NF_STATUS error code on fail.
Windows API function GetLastError() returns an extended error code in case if the function returns NF_STATUS_FAIL.
When the flag NFF_DISABLE_AUTO_REGISTER is enabled using nf_setOptions, any application that uses driver API tries to register the driver automatically during a call to nf_init, if it is not yet registered. The administrative rights are required to perform this operation. The driver starts immediately after registration, and reboot is not required. The driver will be loaded automatically on each system start. When the driver is registered and started, a client process doesn't require administrative rights for using it via API.
