...so, for any non-Boolean parameter specific to your extcap program, *DO NOT MAKE THE ARGUMENT TO THE OPTION OPTIONAL*. (For Boolean options, the extcap code either passes the option, *without* an argument, if the parameter is true, or doesn't pass the option at all if the parameter is false, so "optional argument" works, even with the *BSD/macOS getopt_long().) For example, if you're using getopt_long() to parse your arguments, *DO NOT* use optional_argument for *ANY* non-Boolean options. ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev () wireshark org> Archives: https://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://www.wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-request () wireshark org?subject=unsubscribe
