question about code

[borgit]

I am referring to the HostAP driver code, specifically we are working with
version 0.3.7.  What we want to do is to send a couple of integers in the
payload of a broadcast packet that we have created.  And to do this we need
to convert them to a string, because as far as I understand we can only send
strings.  Thanks for your idea of using the simple_strto* family of
functions, and I totally forgot about the sprintf function for int to string
conversion, it should work good.

Thanks again.

What exactly are you referring to with "hostAP"? Host AP driver, i.e.,
kernel code? Standard C libraries are not generally available in
kernel.. What kind of integer/string conversion do you need in the
kernel? In many cases, I would expect there to be a better way of doing
this and the conversion could be avoided completely.

linux/kernel.h has prototypes for number of related functions
(simple_strto* family for string->int and sprintf for int->string).
