The IsValidLocale function applies a validity test to a locale identifier. The dwFlags parameter determines the nature of the validity test. Currently, the function tests whether a locale identifier is installed or supported on the calling system.
BOOL IsValidLocale(
LCID Locale, // locale identifier to validate
DWORD dwFlags // specifies validity test
);
Value | Meaning |
---|---|
LCID_INSTALLED | Test whether the locale identifier is both supported and installed. |
LCID_SUPPORTED | Test whether the locale identifier is supported. |
If the locale identifier passes the specified validity test, the return value is nonzero.
If the locale identifier does not pass the specified validity test, the return value is zero.
If the LCID_INSTALLED flag is specified and this function returns a nonzero value, the locale identifier is both supported and installed on the system.
If the LCID_SUPPORTED flag is specified and this function returns zero, the locale identifier is supported in the release, but not necessarily installed on the system.
