UILANGUAGE_ENUMPROCA callback function (winnls.h)
An application-defined callback function that processes enumerated user interface language information provided by the EnumUILanguages function. The UILANGUAGE_ENUMPROC type defines a pointer to this callback function. EnumUILanguagesProc is a placeholder for the application-defined function name.
Syntax
UILANGUAGE_ENUMPROCA UilanguageEnumproca;
BOOL UilanguageEnumproca(
LPSTR unnamedParam1,
LONG_PTR unnamedParam2
)
{...}
Parameters
unnamedParam1
unnamedParam2
Return value
Returns TRUE to continue enumeration or FALSE otherwise.
Remarks
An EnumUILanguagesProc function can carry out any task. The application registers this function by passing its address to the EnumUILanguages function.
If MUI_LANGUAGE_ID was specified in the call to EnumUILanguages, the language strings passed to this function will be hexadecimal language
identifiers that do not include the leading 0x, and will be 4 characters in length. For example, en-US will
be passed as "0409" and en as "0009".
C# Signature
delegate System.Boolean EnumUILanguagesProc(
System.IntPtr lpUILanguageString,
System.IntPtr lParam
);
Note
The winnls.h header defines UILANGUAGE_ENUMPROC as an alias which automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
