C function that gives the device class depending on the major number of the device file

[Navecric]

Hi all,

Is there any C function/macro in HPUX that gives us the device file class depending on its major number.

lsdev gives us the major number and its corresponding device class. But, I'm looking for a C function that does the same rather than manipulating lsdev output string in my program.

Can some one please help me on this

Thanks,
Naveen

Hi Naveen:

Since 'lsdev' can do the heavy-lifting and "understands" driver information, I don't see anything wrong with using a 'popen()' library call to collect the information to parse. Why re-invent a wheel?

Regards!

Have you looked into any of the 11.31 libIO(3) functions?

It looks like you were successful, see your previous thread:

Hi Dennis,

Sorry missed your reply. Yeah i was able to use libIO APIs to get the information.

Thanks for the suggestion
