I did it,
I don't know why, but the string "user=%s&pass=%s" was creating a segmentation fault, what i did was specify which characters i wanted to seek, like this:
Code:
/* compile gcc file.c -o file.cgi
* Get strings from html form
*/
#include <stdio.h>
#include <stdlib.h>
int main(void){
char *data, str1[12], str2[12];
printf("%s%c%c\n","Content-Type:text/html;charset=iso-8859-1",13,10);
data = getenv("QUERY_STRING");
if(data==NULL){
printf("<H1>Error passing data to CGI Script</H1>");
exit(1);
}
else
sscanf(data,"user=%[0-9a-zA-Z]&pass=%[0-9a-zA-Z]", &str1, &str2);
printf("Username: %s<BR>", str1);
printf("Password: %s<BR>", str2);
return(0);
}
I have a string
Form this string, I want to extract
I am unable to do that with sscanf because of the space between the words. What else can I use?
#include <stdio.h>
char buf_2;
int
main()
{
char *buf_1 = "\\\\?\\whats going on";
sscanf(buf_1,... (4 Replies)
I need to match a float inside a very long string (about 5000 chars) with sscanf. (I trimmed the string in this example.) I can't seem to match all the chars that come before and after the float.
int main(void)
{
char A = "";
strcat(A, " hello world! WORD' name='5.3498' hello world! ... (1 Reply)
sscanf does not stop at the first "&". How can I extract "doe" ?
char A = "name=john&last=doe&job=vacant&";
char B = "last";
char C = "";
char *POINTER = strstr(A, B);
sscanf(POINTER + strlen(B), "=%s%*", C);
printf("%s\n", C); // doe&job=vacant& (2 Replies)
How can I separetely extract the string and int after "dribble" ? (sscanf must limit TEXT to 9 chars to avoid buffer overflows.)
How come this code does not work with "dribbletext08" but does with "dribbletext05" ?
int main(void)
{
char TEXT = "";
int NUMBER = 0;

Hi with the following code
int a, b;
while ((n = readline (connfd, buf, sizeof(buf)-1)) > 0)
{
buf = '\0';
if (sscanf(buf,"%d %d",&a,&b) != 2)
snprintf (buf, sizeof(buf), "data error\r\n");
else
{
printf("\nRecvd %d and %d",a,b);

AppConfig::CGI(3) User Contributed Perl Documentation AppConfig::CGI(3)NAME
AppConfig::CGI - Perl5 module for processing CGI script parameters.
SYNOPSIS
use AppConfig::CGI;
my $state = AppConfig::State->new(\%cfg);
my $cgi = AppConfig::CGI->new($state);
$cgi->parse($cgi_query);
$cgi->parse(); # looks for CGI query in environment
OVERVIEW
AppConfig::CGI is a Perl5 module which implements a CGI interface to AppConfig. It examines the QUERY_STRING environment variable, or a
string passed explicitly by parameter, which represents the additional parameters passed to a CGI query. This is then used to update
variable values in an AppConfig::State object accordingly.
AppConfig::CGI is distributed as part of the AppConfig bundle.
DESCRIPTION
USING THE AppConfig::CGI MODULE
To import and use the AppConfig::CGI module the following line should appear in your Perl script:
use AppConfig::CGI;
AppConfig::CGI is used automatically if you use the AppConfig module and create an AppConfig::CGI object through the cgi() method.
AppConfig::CGI is implemented using object-oriented methods. A new AppConfig::CGI object is created and initialised using the new()
method. This returns a reference to a new AppConfig::CGI object. A reference to an AppConfig::State object should be passed in as the
first parameter:
my $state = AppConfig::State->new();
my $cgi = AppConfig::CGI->new($state);
This will create and return a reference to a new AppConfig::CGI object.
PARSING CGI QUERIES
The "parse()" method is used to parse a CGI query which can be specified explicitly, or is automatically extracted from the "QUERY_STRING"
CGI environment variable. This currently limits the module to only supporting the GET method.
See AppConfig for information about using the AppConfig::CGI module via the cgi() method.
