Which lib contains function

'ello all.

Coming from a Microsoft VC++ backround I have great difficulty
in finding the right libraries to include when I want to use a certain function on Linux.With Microsoft you gave a HUGE help system with this type of information.

I can use :

nm -og *so | grep <funcname>
to search for exported symbols, but what if I have not got the lib?

The man pages does not really help...

TIA

have a look at apropos, it searches man pages. you could also add a for-loop to your above method to search every executable on the system.

Thanks Kev.

I eventually did this :

find / -name *.so.* | xargs nm -Dog | grep -i <funcname>

It searches my whole file system ( .so files only though ) for the the func name.
Luckily I got a P4.Not sure what this will do to a 486.
Any suggestions on the command?
