Returns the parameters posted to the CGI script


Returns a list of Name=Value pairs, where Name is an atom and Value is a string, representing the information that was posted to the CGI script. Both POST and GET methods are supported.

If there is a problem, the predicate fails. In that case, the caller should retrieve an error message using get_error_output/1 and present it to the user, e.g. by embedding it into the generated html page.

Fail Conditions
