feng shui of linux

Since I am presently unable to help anyone out with true linux type concerns. I humbly present this to
cyberSpace:

Kidco and spinich pesto: I use this manual_labor_pablum_making_device purchased from kidco to make
a garlic_spinach_sunflowerseed_veg.oil_salt pesto spread to be applied to toasted and buttered home made
bread. I find it to be excellent.

I started to read chapter5 of the LDD. Switched over to trying to communicate between 2 c++ program and
ended up getting something to work with socketpairs. Here is an informative site for me:
http://codeidol.com/unix/unix-networ...g-Descriptors/
and then here for some code to work with threads:

Many and probably most of the man pages work on the linuxside lfs but when I type

man pthread_create ( or most any other pthread... ) the console returns

No manual entry for pthread(whatever)

However pthread_create.3p is in /usr/share/man/man3p - and it comes up on the console using:

man /usr/share/man/man3p/pthread_create.3p

I took the man_db source out and looked at man.c and nothing jumped out saying here is the prob.
There are probably other man pages that lay
similarly unobserved but at least I now know there is a problem.
