## Member Function Documentation

const ArgumentList& mysqlpp::CommandLineBase::extra_args | ( |  | ) | const
| inline

Get reference to list of command line arguments past the last flag and its possible argument.

Public interface

void mysqlpp::CommandLineBase::parse_error | ( | const char * | message = `0` | ) |
| protected

Called by a subclass when encountering a command line parsing error.

Prints the passed message, calls subclass's print_usage(), and marks the object as no longer successful.
