Wireshark-dev: Re: [Wireshark-dev] What do you use to get a boolean

I have not got as far as getting the value of the boolean, I was was looking for a function to extract it.

I am also not sure if 'value' really is the value of the boolean or the value of the byte containing the boolean (along with other data)?

Actually the last 'value' is, well, the value of the boolean (on the
system running Wireshark).  You must have already pulled out 'value'
using one of the tvb functions (and bit shifted it, if necessary).
