cgiGetValue - Return the value of a CGI variable
char *cgiGetValue (s_cgi *parms, const char *name);
This routine returns a pointer to the value of a cgi variable. Encoded
characters (%nn) are already decoded. One must not free the pointer.
If 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.
Memory allocated by the returned value is automatically freed by the
final call to cgiFree(3).
On success a pointer to a string is returned. If the variable wasn’t
transmitted through CGI or was empty NULL is returned.
This CGI library is written by Martin Schulze <firstname.lastname@example.org>. If
you have additions or improvements please get in touch with him.
