Programming

Hi, I do the following:
i) malloc some parameter structures
ii) fork
iii) in the child, I call execvp using these parameters
obviously, here I can never free() the structures as execvp should not return
iiii) I am currently doing waitpid in parent then freeing, but this does not seem to work well (MATLAB complains - this is a MEX function; if I don't it seems to be okay)

My question: when am I supposed to free these parameters? Am I not?

Thank you

You can free the parameters in the parent process any time after you've fork()'d. After that, the child has its own copies to work from (which, as you say, don't need to be free()'d) and the parent has allocated memory it's not going to use, so it can be free()'d straight away.

What exactly does MATLAB complain about?
