Ctrl-C in mex not working

Hi,

I am trying to make it possible to break out of my mex function using ctrl-c. I have tried using the undocumented uc MATLAB library (as detailed here: https://undocumentedmatlab.com/blog/mex-ctrl-c-interrupt ), however the sample program does not detect ctrl-c.

I have also tried adding my own SIGINT handler (see: https://linuxtoosx.blogspot.com/2010/10/ctrl-c-signal-catching-from-c-program.html ). This doesn't work either.

I have tried this on macOS 10.13.4, in MATLAB versions 2018a, 2017b and 2016a. I've also tried it on Windows 10 in MATLAB 2018a.

The last posts I see online about this are from 2016. Has anyone had any more recent luck doing this? If so, please advise on how to make it work!

Thanks, Ian

Hi Ian,

I am assuming that you would like to kill the MEX function without killing the MATLAB process. In this case the following link should be useful: https://www.mathworks.com/matlabcentral/answers/221744-killing-a-mex-function-when-it-doesn-t-respond-to-ctrl-c-or-ctrl-break-under-win64?s_tid=answers_rc1-2_p2_MLT

Hi Sid,

Thanks for responding. I am indeed trying to break out of a mex function I am writing without killing MATLAB. The forum link you provided links to variations on the same information in the first link I provided. I have implemented this and am not having any luck in getting it to work, including the demo code that works for others.

Thanks, Ian
