Function Documentation

ostream& operator<< (  ostream &  os, arg_parser &  ap )  [inline]

Errors are dealt with as well. The variables can either be boolean, char*, or dl_list<char*>; which type a variable is is determined by a value of the enumerated type arg_parser::arg_type. Here is an example of the use of this class: bool arg1; // These must be static or global scope... bool arg2; char *arg3; arg_parser::arg_record arg_list[] = { { "-arg1", &arg1, arg_parser::BOOLEAN }, { "-arg2", &arg2, arg_parser::BOOLEAN }, { "-arg3", &arg3, arg_parser::STRING }, { NULL, NULL } }; int main( int argc, char *argv[] ){ arg1 = true; // default initialization must occur before the arg2 = false; // arg_parser is called! arg3 = NULL; arg_parser ap( arg_list ); ap.check_args( argc, argv );
