Description jreiser 1999-10-17 03:21:58 UTC 
There are two global symbols 'pthread_create'
and two global symbols 'pthread_attr_init'
in /lib/libpthread-0.8.so .

$ nm -D /lib/libpthread-0.8.so | grep pthread_create
00006c34 T pthread_create
00006354 T pthread_create
$

and similarly for pthread_attr_init.  This is wasted space,
and possibly a logic bug (if in either case the two are
not duplicates of each other).
Comment 1 Cristian Gafton 2000-01-05 01:29:59 UTC 
Those are really

00006794 T pthread_create@@GLIBC_2.1
000070e4 T pthread_create

In other words, versioned implementations of the same function for backwards
compatibility.
