curl::option CurlHandle,"POSTFIELDS","name=Edmund+Nielsen+Bohr&address=Downing+street+11"
Pass a string as parameter, which should be the full data to post in a HTTP post operation.
Note that CURL library also implements the option CURLOPT_POSTFIELDSIZE for C programmers. That option is automatically called by the interface function, thus any binary BASIC string can be used as post parameter.
