Write to same mat file from multiple compiled functions

I am compiling multiple functions (using MCC) to retrieve data from a MySQL server in order to parallelize the process. Each function will write data to a mat file. Is there a way I can check if the mat file is not in memory of another function before loading it.

My first thought would be that global variables could solve this. My second thought is that global variables can generally be avoided in favor of a more robust solution.
I don't think that would work, as each function will run in a different instance of MATLAB runtime.
If the instances are separated, I hope they won't have access to each others memory, so what you are asking is impossible.
Is there some way to lock a mat file, so I can have a while loop checking when I should load it.
