As part of my engineering project, we need to read a device file (which is tied to an accelerometer) and retrieve data from the file.
The problem that I encountered is that the kernel will freeze the thread/process waiting for new data from the accelerometer - which potentially could never come say if the accelerometer fails.
My question is how to implement a timeout on reading the data without having to multi-thread the program.
Any ideas?
