DLERROR(3)            DragonFly Library Functions Manual            DLERROR(3)

NAME
     dlerror -- retrieve dynamic linker error messages

LIBRARY
     This function is not in a library.  It is included in every dynamically
     linked program automatically.

SYNOPSIS
     #include <dlfcn.h>

     char *
     dlerror(void);

DESCRIPTION
     The dlerror() function returns a null-terminated character string
     describing the last error that occurred during a call to dlopen(),
     dladdr(), dlinfo(), dlsym(), dlvsym(), or dlclose().  If no such error
     has occurred, dlerror() returns a null pointer.  At each call to
     dlerror(), the error indication is reset.  Thus in the case of two calls
     to dlerror(), where the second call follows the first immediately, the
     second call will always return a null pointer.
