hmm, so you mean that these are function call statements? or is it a function prototype? Yes, i was aware about the data type of the function prototype, but since I never tried OpenSSL before, so i just try and see the error is. Silly me :-)
I tried to put the statement in the main block, but then an error message displayed "undefined reference to 'OpenSSL_add_all_algorithm" and "undefined reference to 'SSL_load_error_strings' Is there any linkage i forgot to put? Anyway, thanks for the reply.
