When callingFormatMessage()withFORMAT_MESSAGE_FROM_SYSTEMandGetLastError(), this does not seem possible. One idea: CallFormatMessage()with a 8196 char/wchar_t stack-allocated buffer. On failure, callFormatMessage()again with flagFORMAT_MESSAGE_ALLOCATE_BUFFER. It seems hard to believe ...
FORMAT_MESSAGE_FROM_STRING: 0x00000400 Pointer to a string that consists of unformatted message text. It will be scanned for inserts and formatted accordingly. 假设这两个都没有指定的话,那么lpSource參数就会被忽略 <3>dwMessageId 错误ID。假设dwFlags中指定了FORMAT_MESSAGE_FROM_STRING,那么该值就会被...
FORMAT_MESSAGE_FROM_STRING Specifies thatlpSourceis a pointer to a null-terminated message definition. The message definition may contain insert sequences, just as the message text in a message table resource may. Cannot be used with FORMAT_MESSAGE_FROM_HMODULE or FORMAT_MESSAGE_FROM_SYSTEM. ...
