Need Help in Loading driver

poojapatel · 08-02-2006, 01:20 AM

Hello friends,

i had newly joined the group and its very useful.

i am new to linux programming and i want to load the device drivers programatically. Is there any function to load the driver.

I also want to check whether the driver for particular device is loaded or not and in some case i need to take the handle of the loaded drivers and i have to unload it through program.

can anyone help me in this field. I am using the linux(Fedora 4.0) OS.

Thanks in advance.........

Code:

# man modprobe
NAME
       modprobe - program to add and remove modules from the Linux Kernel

# man lsmod
NAME
       lsmod -- program to show the status of modules in the Linux Kernel

These two might be all you need. The ability to unload modules is fairly new in the kernel (I think), so may not be enabled by default in the kernel configuration. If not, you'll need to build your own kernel. There may be information in:

Code:

# zcat /proc/config.gz

And, the drivers in question might be built into the kernel (not as modules), in which case you'd need to build your own kernel, specifying them as modules.
