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!!!

hobbit-ackinfo.cgi

HOBBIT-ACKINFO.CGI(1)					      General Commands Manual					     HOBBIT-ACKINFO.CGI(1)

NAME

       hobbit-ackinfo.cgi - Xymon CGI script to acknowledge alerts

SYNOPSIS

       hobbit-ackinfo.cgi

DESCRIPTION

       hobbit-ackinfo.cgi is invoked as a CGI script via the hobbit-ackinfo.sh CGI wrapper.

       hobbit-ackinfo.cgi  is  used  to  acknowledge an alert on the Xymon "Critical Systems" view, generated by the hobbit-nkview.cgi(1) utility.
       This allows the staff viewing the Critical Systems view to acknowledge alerts with a "Level 1" alert, thereby removing the alert  from  the
       Critical Systems view.

       Note that the Level 1 alert generated by the hobbit-ackinfo.cgi utility does NOT stop alerts from being sent.

       In a future version of Xymon (after Xymon 4.2), this utility will also be used for acknowledging alerts at other levels.

OPTIONS

       --level=NUMBER
	      Sets  the  acknowledgment  level. This is typically used to force a specific level of the acknowledgment, e.g. a level 1 acknowledge
	      when called from the Critical Systems view.

       --validity=TIME
	      Sets the validity of the acknowledgment. By default this is taken from the CGI parameters supplied by the user.

       --sender=STRING
	      Logs STRING as the sender of the acknowledgment. By default, this is taken from the loginname of the webuser sending the acknowledg-
	      ment.

       --env=FILENAME
	      Loads the environment defined in FILENAME before executing the CGI script.

       --area=NAME
	      Load environment variables for a specific area. NB: if used, this option must appear before any --env=FILENAME option.

       --debug
	      Enables debugging output.

ENVIRONMENT VARIABLES

       BBHOME Used to locate the template files for the generated web pages.

       QUERY_STRING
	      Contains the parameters for the CGI script.
