This flag only takes effect without \fBTERMKEY_FLAG_NOTERMIOS\fP; with it, none of the signal keys are disabled anyway. .PP When the constructor is invoked, it attempts to detect if the current locale is UTF-8 aware or not, and sets either the \fBTERMKEY_FLAG_UTF8\fP or \fBTERMKEY_FLAG_RAW\fP flag. One of these two bits will always be in effect. The current flags in effect can be obtained by \fBtermkey_get_flags\fP(). .SH VERSION CHECK MACRO |
