FindNLSString function
Locates a Unicode string (wide characters) or its equivalent in another Unicode string for a locale specified by identifier.
Syntax
int FindNLSString( _In_ LCID Locale, _In_ DWORD dwFindNLSStringFlags, _In_ LPCWSTR lpStringSource, _In_ int cchSource, _In_ LPCWSTR lpStringValue, _In_ int cchValue, _Out_opt_ LPINT pcchFound );
Parameters
- Locale [in]
-
Locale identifier that specifies the locale. You can use the MAKELCID macro to create an identifier or use one of the following predefined values.
Windows Vista and later: The following custom locale identifiers are also supported.
- dwFindNLSStringFlags [in]
-
Flags specifying details of the find operation. For detailed definitions, see the dwFindNLSStringFlags parameter of FindNLSStringEx.
- lpStringSource [in]
-
Pointer to the source string, in which the function searches for the string specified by lpStringValue.
- cchSource [in]
-
Size, in characters excluding the terminating null character, of the string indicated by lpStringSource. The application cannot specify 0 or any negative number other than -1 for this parameter. The application specifies -1 if the source string is null-terminated and the function should calculate the size automatically.
- lpStringValue [in]
-
Pointer to the search string, for which the function searches in the source string.
- cchValue [in]
-
Size, in characters excluding the terminating null character, of the string indicated by lpStringValue. The application cannot specify 0 or any negative number other than -1 for this parameter. The application specifies -1 if the search string is null-terminated and the function should calculate the size automatically.
- pcchFound [out, optional]
-
Pointer to a buffer containing the length of the string that the function finds. For details, see the pcchFound parameter of FindNLSStringEx.
Return value
Returns a 0-based index into the source string indicated by lpStringSource if successful. In combination with the value in pcchFound, this index provides the exact location of the entire found string in the source string. A return value of 0 is an error-free index into the source string, and the matching string is in the source string at offset 0.
The function returns -1 if it does not succeed. To get extended error information, the application can call GetLastError, which can return one of the following error codes:
- ERROR_INVALID_FLAGS. The values supplied for flags were not valid.
- ERROR_INVALID_PARAMETER. Any of the parameter values was invalid.
- ERROR_SUCCESS. The action completed successfully but yielded no results.
