modprobe question

Hi All;
I have a program that relies of some modules being loaded. is there a
modprobe() or anything similar? I'm trying to avoid a system("modprobe...")
type call
Thanks
Pat

I suggest running your modprobe command under strace and watching what
system calls it does.  man init_module for one of them.  What is your
objection to system("modprobe") anyway?

Beware that you can make your program less portable if you do this
since the kernel interface is subject to change while the modprobe
program tries to present a consistent interface.  See the "backwards
compatibility" section in the modprobe man page.

I guess you're talking about Linux here. If that assumption is correct
you shouldn't have to invoke modprobe at all - if things are set up
correctly (major device number is associated with the module in the
/etc/modules.conf file) then the module should be loaded automatically
the moment (unless is already is) the device file gets opened.
