NAME

       cgiGetVariables - Returns a list of CGI variables

SYNOPSYS

       #include <cgi.h>

       char **cgiGetVariables (s_cgi *parms);

DESCRIPTION

       This  routine  returns  a  NULL	terminated  array  of CGI variables that are available.  To get the value of a variable you'll have to use
       cgiGetValue(3).	To free the memory allocated use cgiFreeList(3).

RETURN VALUE

       On success a NULL terminated array of strings is returned.  The last element is set to NULL.  If an error occurred or if no  variables  are
       available NULL is returned.

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.
