// This file contains:
// 1) functions to clear and parse the various structs
// 2) actual GUI RPCs

// The core client expects all data to be formatted in the "C" locale,
// so each GUI RPC should get the current locale, then switch to the
// "C" locale before formatting messages or parsing results.
// After all work is completed, revert back to the original locale.
//
// Template:
//
// int RPC_CLIENT::template_function( args ) {
//     int retval;
//     SET_LOCALE sl;
//     char buf[256];
//     RPC rpc(this);
//
//     <do something useful>
//
//     return retval;
// }
//
// NOTE: Failing to revert back to the original locale will cause
//   formatting failures for any software that has been localized or
//   displays localized data.
