1.  I have to check, but I think so

2. Actually, this is a slight mis-conception from my documentation which I need to fix tonight. pmt_integer() is not a public member of the PMT class. You need to use pmt_from_long(X) which will return you a pmt_t which is an instance of a pmt_integer. I need to make this clear and update my documentation.

If you look at any of the inband code or my MAC examples, you will always see pmt_from_long() and pmt_to_long()

Thanks for coming up with the doc so fast. This helped a lot!

A few comments:

1. In section "Constructing / Assigning a PMT": isn't pmt_list part of
this too?

2. In "PMT Conversion Methods": what's the difference between using a
"construction method" and a "conversion method" to generate a PMT type?
For example, one can use either pmt_integer(long) or pmt_from_long() to
get a pmt long type.

Hi all,

I've added documentation on the new polymorphic type in GNU Radio, PMT, to the GNU Radio wiki:

It has full details of many of the methods, how to use a PMT, how to assign it values, how to do type conversions, etc...

For more difficult PMT types (lists, dictionaries, etc...), I have added detailed sections.

This is all part of my attempt to make a better wiki...

... I'm branching out from the m-block info, slowly but surely!
