dlerror(3X)            UNIX System V(C Development Set)             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, results in NULL
      being returned.

SEE ALSO
      dlclose(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.
