Register function to be called when MEX-function cleared or MATLAB terminates
C Syntax
Arguments
ExitFcn
Pointer to function you want to run on exit.
Returns
Description
Use mexAtExit
to register a C function to be called just before the MEX-function is cleared or MATLAB is terminated. mexAtExit
gives your MEX-function a chance to perform tasks such as freeing persistent memory and closing files. Typically, the named ExitFcn
performs tasks like closing streams or sockets.
Each MEX-function can register only one active exit function at a time. If you call mexAtExit
more than once, MATLAB uses the ExitFcn
from the more recent mexAtExit
call as the exit function.
If a MEX-function is locked, all attempts to clear the MEX-file will fail. Consequently, if a user attempts to clear a locked MEX-file, MATLAB does not call the ExitFcn
.
