cgi_init

cgi_init(3)							     cgi/cgi.h							       cgi_init(3)

NAME

       cgi_init  - Initialize ClearSilver CGI environment

SYNOPSIS

       #include <cgi/cgi.h>

       NEOERR *cgi_init (CGI **cgi, HDF *hdf);

ARGUMENTS

       cgi - a pointer to a CGI pointer
       hdf_file - the path to an HDF data set file that will also be
       loaded into the dataset.  This will likely have to
       a be a full path, as the HDF search paths are not
       yet set up.  Certain things, like

DESCRIPTION

       cgi_init  initializes  the ClearSilver CGI environment, including creating the HDF data set.  It will then import the standard CGI environ-
       ment variables into that dataset, will parse the QUERY_STRING into the data set, and parse the HTTP_COOKIE into the data set.  Note that if
       the  var  xdisplay  is in the form data, cgi_init will attempt to validate the value and launch the configured debugger on the CGI program.
       These variables have to be specified in the hdf_file pointed to by hdf_file.  The default settings do  not  allow  debugger  launching  for
       security reasons.

RETURN VALUE

       cgi - an allocated CGI struct, including
