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.
