NLS: 이름 기반 API 샘플

아티클
06/13/2023

이 항목에 설명된 샘플 애플리케이션은 NLS "로캘 이름" 함수 중 일부를 보여 줍니다. 가능하면 애플리케이션에서 로캘 식별자 대신 로캘 이름을 사용해야 합니다.

샘플 애플리케이션은 EnumSystemLocalesEx 를 사용하여 추가 로캘을 포함하여 운영 체제의 모든 로캘을 열거합니다.

애플리케이션에서 지원하는 열거형 콜백 함수는 하나 이상의 로캘 이름을 매개 변수로 사용할 수 있습니다. EnumSystemLocalesEx 는 선택적 lparam 값의 콜백 함수에 이러한 이름을 전달합니다. 사용자가 명령줄에서 로캘을 입력하는 경우 콜백 함수는 모든 로캘을 표시하는 대신 지정된 로캘만 표시합니다.

표시된 각 로캘에 대해 콜백 함수는 시스템 로캘인지 여부를 보고하고, 로캘의 기본 형식을 사용하여 현재 날짜를 인쇄하고, Windows Vista에 도입된 각 로캘 정보 상수 (예: LOCALE_SSCRIPTS)에 로캘에 대한 모든 데이터를 표시합니다.

샘플 애플리케이션은 입력 로캘을 구문 분석하여 IsValidLocaleName을 사용하여 유효한지 확인합니다.

이 샘플에서는 다음 함수를 보여 줍니다.
