Function Documentation

dissect_opts_handle_opt()

bool dissect_opts_handle_opt ( int  opt, char *  optarg_str_p  )

extern

Handle a command line option.

An error message is reported with cmdarg_err() if it's not valid.

Parameters

opt	The option character or integer value.
optarg_str_p	The string argument provided with the option, if any.

Returns

True if the option is valid, false if not.

setup_enabled_and_disabled_protocols()

bool setup_enabled_and_disabled_protocols ( void  )

extern

Set up disabled protocols and enabled/disabled heuristic protocols as per specified command-line options.

Returns

True if all specified heuristic protocols exist, false otherwise.
