Hello Gururaj,

getopt is a utility function from the Unix library, and optarg is
a global variable associated with this function. Try including
clib/getopt.c from the Berkeley DB source distribution, it's
a replacement for systems that don't have getopt.

You might also look at the build_windows/ex_access.dsp
project file in the source distribution, it is used to build the
examples, and it includes getopt.c.

Hi Don,
I tried including "clib/getopt.c" but i am getting the below errors, i
looked into the file "getopt.c" as well, but cud not find any
identifiable errors, if i am compiling just the "getopt.c" then it
compiles fine except for some warnings

Hi Don,
Thanks for ur help, i was able to fix the problem, the "clib/getopt.c"
had some problems so i just added these function definitions into my
code and now it works fine.

Thanks,
Gururaj
