Writing to MMC/SD from a background process
I am running a background process, and I am trying to write to the MMC/SD card from this process, but it doesn't work. What's the matter?
The events system is used to access the Multimedia Card. When the program is launched from the shell, the shell is already "linked" with the events system, and handles events. That is not the case if a program is run in the background (for example launched with exec() or exec2()) and you have to activate it, in the following way: just add event_connect_to_task(); at the beginning of the called program(s) and event_disconnect(); at the end.
This will be automatic in a future version of VCRT.
