/**
|

* @name K32LoadStringExW
|
||||
* Loads a string resource from the executable file associated with a
|
||||
* specified module, copies the string into a buffer, and appends a
|
||||
* terminating null character.
|
||||
* This is basically the LoadString() API ripped from user32.dll to
|
||||
* remove any dependency of ConUtils from user32.dll, and to add support
|
||||
* for loading strings from other languages than the current one.
|
||||
*
|
||||
* @param[in] hInstance
|
||||
* Optional handle to an instance of the module whose executable file
|
||||
* contains the string resource. Can be set to NULL to get the handle
|
||||
* to the application itself.
|
||||
*
|
||||
* @param[in] uID
|
||||
* The identifier of the string to be loaded.
|
||||
*
|
||||
* @param[in] LanguageId
|
||||
* The language identifier of the resource. If this parameter is
|
||||
* <tt>MAKELANGID(LANG_NEUTRAL, SUBLANG_NEUTRAL)</tt>, the current language
|
||||
* associated with the calling thread is used. To specify a language other
|
||||
* than the current language, use the @c MAKELANGID macro to create this
|
||||
* parameter.
|
||||
*
|
||||
* @param[out] lpBuffer
|
||||
* The buffer that receives the string. Must be of sufficient length
|
||||
* to hold a pointer (8 bytes).
|
||||
*
|
||||
* @param[in] nBufferMax
|
||||
* The size of the buffer, in characters. The string is truncated and
|
||||
* NULL-terminated if it is longer than the number of characters specified.
|
||||
* If this parameter is 0, then @p lpBuffer receives a read-only pointer
|
||||
* to the resource itself.
|
||||
*
|
||||
* @return
|
||||
* If the function succeeds, the return value is the number of characters
|
||||
* copied into the buffer, not including the terminating null character,
|
||||
* or zero if the string resource does not exist. To get extended error
|
||||
* information, call GetLastError().

/**
|
||||
* @name FormatMessageSafeW
|
||||
* Loads and formats a message string. The function requires a message
|
||||
* definition as input. The message definition can come from a buffer
|
||||
* passed to the function. It can come from a message table resource in
|
||||
* an already-loaded module, or the caller can ask the function to search
|
||||
* the system's message table resource(s) for the message definition.
|
||||
* Please refer to the Win32 FormatMessage() function for more details.
|
||||
*
|
||||
* @param[in] dwFlags
|
||||
* The formatting options, and how to interpret the @p lpSource parameter.
|
||||
* See FormatMessage() for more details.
|
||||
*
|
||||
* @param[in] lpSource
|
||||
* The location of the message definition. The type of this parameter
|
||||
* depends upon the settings in the @p dwFlags parameter.
|
||||
*
|
||||
* @param[in] dwMessageId
|
||||
* The message identifier for the requested message. This parameter
|
||||
* is ignored if @p dwFlags includes @b FORMAT_MESSAGE_FROM_STRING.
|
||||
*
|
||||
* @param[in] dwLanguageId
|
||||
* The language identifier for the requested message. This parameter
|
||||
* is ignored if @p dwFlags includes @b FORMAT_MESSAGE_FROM_STRING.
|
||||
*
|
||||
* @param[out] lpBuffer
|
||||
* A pointer to a buffer that receives the null-terminated string that
|
||||
* specifies the formatted message. If @p dwFlags includes
|
||||
* @b FORMAT_MESSAGE_ALLOCATE_BUFFER, the function allocates a buffer
|
||||
* using the LocalAlloc() function, and places the pointer to the buffer
|
||||
* at the address specified in @p lpBuffer.
|
||||
* This buffer cannot be larger than 64kB.
|
||||
*
|
||||
* @param[in] nSize
|
||||
* If the @b FORMAT_MESSAGE_ALLOCATE_BUFFER flag is not set, this parameter
|
||||
* specifies the size of the output buffer, in @b TCHARs.
|
||||
* If @b FORMAT_MESSAGE_ALLOCATE_BUFFER is set, this parameter specifies
|
||||
* the minimum number of @b TCHARs to allocate for an output buffer.
|
||||
* The output buffer cannot be larger than 64kB.
|
||||
*
|
||||
* @param[in] Arguments
|
||||
* Optional pointer to an array of values describing a variable number of
|
||||
* arguments, depending on the message string. Each argument is used to
|
||||
* replace an <em>insert sequence</em> in the message string.
|
||||
* By default, the @p Arguments parameter is of type @c va_list*, initialized
|
||||
* with va_start(). The state of the @c va_list argument is undefined upon
|
||||
* return from the function. To use the @c va_list again, destroy the variable
|
||||
* argument list pointer using va_end() and reinitialize it with va_start().
|
||||
* If you do not have a pointer of type @c va_list*, then specify the
|
||||
* @b FORMAT_MESSAGE_ARGUMENT_ARRAY flag and pass a pointer to an array
|
||||
* of @c DWORD_PTR values; those values are input to the message formatted
|
||||
* as the insert values. Each insert must have a corresponding element in
|
||||
* the array.
|
||||
*
|
||||
* @return
|
||||
* If the function succeeds, the return value is the number of characters
|

* copied into the buffer, not including the terminating null character,
