    How to test file operations in Linux module

    Hi All,

    I have some doubts regarding how to test file operations in linux module.

    for examples:
    Inside my linux device driver module I have
    1. probe(), open(), read(), write(), ioctl() etc functions. how to test it whether they are working properly.
    Is there particular tools to test each functions or do we need to write user applications to test?

    regards
    soibam

    I can be found either 40 miles west of Chicago, or in a galaxy far, far away.

    You can emit diagnostic messages with the printk() function. You might want to download the Linux Device Drivers, 3rd Edition from O'Reilly. It is available for free download, or you can purchase it from Amazon.com et al.
