Writing into a file from device driver

Hello experts!

I am writing a simple character device driver in C. I wanted to know if there is a way that I can open a text file and then read/write into it from within the driver.

To summarize, I want to:
1. open a text file from within device driver
2. write some debug data into the file
3. close the text file

I am new to linux kernel programming. Please let me know if there is a way to achieve the above tasks.

Regards,
Vikram

Short answer: NO WAY.
Long answer: probably possible but is _very_ difficult and highly unrecommended.

AFAIK you have to use printk() for that

Vikram_B: that was all about files. But as ahoffman say, printk() may help to debug driver. Using this function you can generate kernel log messages, that you may log via syslog or read with 'dmesg' command.
