    Non-Blocking read() in C

    Hello everybody,

    I am trying to read data from an SD card. But the library function of read() is in blocking mode (synchronous). I want to modify this function into non-blocking mode (asynchronous) as it is waste of time waiting for the read operation to complete and I have to do other tasks as well. Its in C.

    Some ideas are to use threading or else. Can anybody give his/her thoughts.

    Any tips and ideas on whats the best way to do it. Any material.

    Thank you in advance.

    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper
