Hi,

I'm trying to make a code for SIMULINK which can use __timeb64 to get timing information and have it compile for use in SIMULINK as a s-function. I'm starting off with the example 'timestwo.c' and placed the call to __timeb64 @ line 70 in the code link below. I also included the necessary libraries (<sys/timeb.h>,<sys/types.h>, time.h)

https://gist.github.com/1061629

When I attempt to compile (in MATLAB using mex timestwo.c) I get the error:

Error timestwo.c: 70 undefined size for `incomplete struct __timeb64 defined at timestwo.c 70 timebuffer' 1 errors, 0 warnings

C:\PROGRA~1\MATLAB\R2009A\BIN\MEX.PL: Error: Compile of 'timestwo.c' failed.

??? Error using ==> mex at 218 Unable to complete successfully.

Any ideas? I'm stuck! (New to compiling .mex functions).

Thanks for any help!

John, perhaps you could add it to the list of upload sites, http://www.mathworks.com/matlabcentral/answers/7924-where-can-i-upload-images-and-files-for-use-on-matlab-answers

@John: Ok, I did not know github before. Usually it is more efficient to post the relevant lines of the code directly. because the readers do not have to trust the link, download a file and open it in an editor.

Hopefully there will be an email notification about new comments in the future. Obviously my "OP has left the building" prejudice was wrong. There was a discouraging number of *other* users, who asked a question, but did not care about comments and answers.
