Hi,
I am getting an error while unloading modules via modprobe. Here is the description of issue.
I have a module 'A' that depends on Module 'C' and 'D'.
And another module 'B' that depends on Module 'C' and 'E'
I loaded these modules from code via 'system' function as
error = system("modprobe -v A");
error = system("modprobe -v B");
After this all my modules A, B, C, D, and E are loaded properly.
Now when i tried to unload module A via
error = system("modprobe -rv A");
This returns an error = 256.
But my module A and D is unloaded successfully. 'C' is not unloaded as it is still in used by 'B'.
Is the error returned by system function is caused due to not unloading of module 'C'? This is a valid scenario and error should not have returned in this case.
I am still trying to find the reason for an error. If anyone has some information on this then please help to share.
Thanks,
Chetan Nanda
