c++ - How to check shared library is loaded successfully or not loaded using dlopen? -

im loading shared library using dlopen() function in c++ program.

then how check loaded or not? or can check loading of library using mangled name of function nowadays in library?

from manual page:

if dlopen() fails reason, returns null.

the dlsym function can not handle c++ identifiers, unless have been declared extern "c", or using mangled name.
