dlerror(3X)                    DG/UX 5.4R3.00                    dlerror(3X)


NAME
       dlerror - get diagnostic information

SYNOPSIS
       cc [flag ...] file ...  -ldl [library ...]

       #include <dlfcn.h>

       char *dlerror(void);

DESCRIPTION
       dlerror 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 dlerror, dlerror returns NULL.  Thus, invoking
       dlerror a second time, immediately following a prior invocation, will
       result in NULL being returned.

SEE ALSO
       dlerror(3X), dlopen(3X), dlsym(3X).

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