Register subroutine to be called when MEX-file cleared or MATLAB terminates
Fortran Syntax
Arguments
ExitFcn
The exit function. This function must be declared as external
.
Returns
Description
Use mexAtExit
to register a subroutine to be called just before the MEX-file is cleared or MATLAB is terminated. mexAtExit
gives your MEX-file a chance to perform an orderly shutdown of anything under its control.
Each MEX-file can register only one active exit subroutine 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-file 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
.
You must declare the ExitFcn
as external
in the Fortran routine that calls mexAtExit
if it is not within the scope of the file.
