       The  dlerror() function returns a human-readable, null-terminated string describing the most recent error
       that occurred from a call to one of the functions in the dlopen API since the  last  call  to  dlerror().
       The returned string does not include a trailing newline.

       dlerror() returns NULL if no errors have occurred since initialization or since it was last called.

       See dlopen(3).

       subsequent dlerror() calls.
