Please pay attention! This method can only be applied to the __stdcall call mode of the output of the C format! 1. Use the VC tool Dumpbin to export the export function table in the DLL to a definition (.def) file EXAMPLE: DUMPBIN VIDEODECODECODLL / EXPROTS /OUT :VIDEODECODER.DEF 2. The exported .def file will be constructed as one. DEF function of the number of exported file EXAMPLE: VideoDeCoder.DEF document reads as follows Dump of file VideoDeCoder.dll file Type: DLL Section contains the following exports for VideoDeCoder.dll 0 characteristics 3D49E48F time date stamp Fri Aug 02 09:46:55 2002 0.00 Version 1 Ordinal Base 11 Number of Functions 11 number of names ordinal hint RVA name 1 0 00010F60 _TM_ClearDecoderBuff @ 4 2 1 00010E80 _TM_CloseDecoder @ 4 3 2 00010F00 _TM_DecodePicture @ 4 4 3 00010ED0 _TM_DecodePictureHeader @ 4 5 4 00010FD0 _TM_GetFileEnd @

Using VC Lib Tools, with /def: (.def File Name) / Machine: IX86 (80x86 machine), outputs a lib file in accordance with VC format. Example: lib /def:videoDecoder.def / Machine: IX864. Time to bring the lib file link; note that when some dynamic library DUMPBIN is only function name, there is no "@nn" parameter format, such as C Builder write The DLL, the output is only the function name symbol, and the link will be wrong when the link is: Error LNK2002: Unresolved External Symbol "FunctionName @ nn" prompts that the function symbols in the prompt cannot be identified, then the corresponding function name in the DEF file is changed to FunctionName @ nn mode, re-establish lib, re-link. This makes it successfully in line with the VC call mode! Reference: MSDN2000 is worth mentioning!
