       dlerror - get diagnostic information

       #include <dlfcn.h>

       char *dlerror(void);

       The  dlerror() function returns a null-terminated character string that
       describes the last error that occurred during dynamic linking  process‐
       ing.  The  returned  string contains no trailing newline. If no dynamic
       linking errors have occurred since the last  invocation	of  dlerror(),
       dlerror()  returns NULL. Thus, invoking	dlerror() a second time, imme‐
       diately following a prior invocation, results in NULL being returned.

       The dlerror() function is one of a family of functions  that  give  the
       user  direct access to the dynamic linking facilities. These facilities
       are available to dynamically-linked  processes  only.  See  Linker  and
       Libraries Guide.

       Linker and Libraries Guide

       The messages returned by	 dlerror() can reside in a static buffer  that
       is  overwritten	on each call to dlerror(). Application code should not
       write to this buffer. Programs wanting to  preserve  an	error  message
       should make their own copies of that message.
