Hello,

I'm facing some problem on the MFS.

I now update to the MQX 4.2.0.2 to hope to resolve these problem.

During this phase, I seen a parameters : MQX_USE_IO_OLD which is set to 1 into My config.h.

Is anybody can say to me what is exactly the impact of this option?

MQX_USE_IO_OLD  set to 1 use the old MQX IO callbacks.

I seen inot the mfs for exemple, this use fseek instead another call.

What is the difference in point of view of the user?
