NAME
       dlerror - get diagnostic information

SYNOPSIS
       #include <dlfcn.h>

       char *dlerror(void);

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

USAGE
       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.

NOTES
       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.
