Synopsis

Gets CGI data input from stdin or the enviorment vairable QUERY_STRING, to form a stream to be used by cgi_fld_by_name, cgi_fld_by_index and cgi_fld_len_by_index functions. After you have finshed with the input stream from this function you should call, cgi_free_input to free it up. Submitted by Scott Beasley jscottb@infoave.com
