       dlerror - get diagnostic information

       [flag ... ] file ...  [library] ...

       is  one of a family of routines that give the user direct access to the
       dynamic linking facilities (using the option on the compiler or command
       line).	returns	 a  null-terminated character string (with no trailing
       newline) that describes the last error  that  occurred  during  dynamic
       linking	processing.  If	 no dynamic linking errors have occurred since
       the last invocation of returns NULL. Thus, invoking second time,	 imme‐
       diately following a prior invocation, results in NULL being returned.

       This routine is thread-safe.

       The  messages  returned	by may reside in a static buffer that is over‐
       written on each call to Application code should not write to this  buf‐
       fer.  Programs  wishing	to preserve an error message should make their
       own copies of that message.

       dlclose(3C), dlopen(3C), dlsym(3C).
