If .B multiple fields are used (i.e. a variable that may contain several values) the value returned contains all these values concatenated together with a newline character as separator. .SH "RETURN VALUE" On success a pointer to a string is returned. If the variable wasn't transmitted through CGI or was empty NULL is returned. .SH "AUTHOR" This cgi library is written by Martin Schulze .
