NAME
cgiInit - Initializes CGI library
SYNOPSYS
#include <cgi.h>
s_cgi *cgiInit ();
DESCRIPTION
This routine initializes the CGI routines. Mainly it reads in and
decodes CGI data for later processing. If the program is not called
via CGI interface the user is prompted to type in CGI variable bindings
via stdin - just like CGI.pm does. There is no limit in the number of
variable bindings.
If HTTP Cookies are used (through the variable HTTP_COOKIE) this
routine will parse them as well and assign them to internal variables.
There is no limit in the number of cookies.
To set a cookie you’ll have to use the cgiSetHeader(3) routine. Some
clients allow 4kB of Cookies while others only allow short ones. Some
clients may also allow only 200 Cookies for a certain domain/path pair.
This routine normally is the first or second that is called from this
library. Only cgiDebug() may be called before. If debugging is
enabled this routine produces some additional output.
The library supports both the regular GET and POST methods as well as
multipart/form-data.
Memory allocated by this library is freed with the cgiFree(3) function.
RETURN VALUE
On success a set of CGI variable bindings is returned that is needed
for later processing. If an error occurs NULL is returned.
