Synopsis

Gets the length of the field data from a CGI input stream based off a field index. The index is from 0 to n. Where 0 would be the first field in the stream, and n would be the last. example: Form snippet: Product <INPUT TYPE="text" NAME="SENDERID" SIZE=80 VALUE="mailto"> Version <INPUT TYPE="text" NAME="VERSION" SIZE=80 VALUE="v1.4"> E-mail <INPUT TYPE="text" NAME="Email" SIZE=80> CGI code to get form field: cgi fld len by index (1, strStdin, &iDataLen, &iNameLen); On return from the call: iDataLen would = 4 and iNameLen would be = 7 Submitted by Scott Beasley jscottb@infoave.com
