The proper solution for this would be: #define CEC_DISABLE "cec_disable" strncmp(str, CEC_DISABLE, strlen(CEC_DISABLE)) but when comparing a string against a string constant strncmp() has no advantage over strcmp() because the comparison is guaranteed to be bound by the string constant. So just replace str strncmp() with strcmp().
