According to
http://people.redhat.com/drepper/dsohowto.pdf
You can restrict exported symbols on Linux (well GNU ld) and Solaris
with something like:
$ gcc -shared -o foo.so -fPIC \
-Wl,--version-script=foo.map ...
Where foo.map looks like :
{
global:
symbol;
another;
local: *;
}
Advantage would be faster loading, and a linux check that makedef.pl
et. al. was up to date.
Has anyone used this in anger, and is it worth doing?
