ОПИСАНИЕ

       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.
