help with sscanf()!

Hi everybody,

i need help with this function, i'm programming in CGI with C and i can't make this work.

QUERY_STRING is something like: user=MYUSER&pass=MYPASS

So, what i want is to store the strings containing the username and the password into str1 and str2 respetively, here's the code:

Code:

#include <stdio.h>
#include <stdlib.h>
 
int main(void){
char *data, *str1, *str2;
 
/*... HTML stuff ...*/
 
data = getenv("QUERY_STRING");
 
if(data==NULL){
printf("<H1>Error passing data to CGI Script</H1>");
exit(1);
}
 
else
sscanf(data, "user=%s&pass=%s", &str1, &str2);
 
printf("Username: %s\n", str1);
printf("Password: %s\n", str2);
return(0);
}

But i'm getting an error... it works perfectly with numbers, but i need it to work like this, with strings.
Am i missing something? Please, help me!!!

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
