Why is the PHP ipc message not in the queue?
In PHP I try to send a message through IPC, and to immediately check if
the message is in the queue. Here is a test code:
$rQueue = msg_get_queue(12345, 0660);
msg_send($rQueue, 0, "test", FALSE, FALSE);
print_r(msg_stat_queue($rQueue));
which prints out the statistics from the given queue, indicating
msg_qnum=0, i.e. no messages in the queue. I expect at least one message
in the queue instead. Where is the problem?

open() system call in C with char array as path appending ? to filename
open() system call in C with char array as path appending ? to filename
I am trying to open (and simultaneously create) a file in C, using a
character array as the path name I pass in which is stored within a node
structure. When I do this, it is appending a question mark to the file
name.
The array specifying the file name is defined as follows:
#define MAX_LENGTH 1024
typedef struct node {
...
char input[MAX_LENGTH]; // filename
...
}
When I initially put the program name in the node structure, I use
makeargv and strcpy as follows:
char **strings;
makeargv(s,":",&strings;
strcpy(n->input,strings[2]);
When I open the file, I try to redirect stdin to it as follows:
char **argumentList;
makeargv(nodes[i]->prog," ",&argumentList);
if (strcmp(nodes[i]->input, "stdin") != 0) {
char* input = nodes[i]->input;
int in = open(input, O_RDONLY);
dup2(in, 0);
int cl = close(in);
I am having trouble understanding if it is something to do with the way I
am passing the pathname in, the attempt to redirect to stdin, or something
else, and I'm having trouble figuring out exactly what the problem
is..could anyone point me in the right direction as to why this may be
happening?

how use regex to get from specific point to end of text?
how use regex to get from specific point to end of text?
I want to know what is the proper regular expression for that :
In an action unprecedented during 12 years of war in Afghanistan, the
commandant of the Marine Corps is firing two top generals. See why:
<a onmouseover="LinkshimAsyncLin.swap()>Generals fired over Taliban attack
</a><br/>security.blogs.cnn.com<br/>There were three investigations of the
incident.
I want to do the following :
give me string starting of a tag which contains
onmouseover="LinkshimAsyncLin.swap() in any position at properties area ..
and end with the end of the remain string .. i mean from this a tag to end
of the string
MY TRY :-
i used this pattern :
<a[^>]*?onmouseover\\s*=\\s*['\"]([^'\"]*?)['\"][^>]*?/?>
it got successfully this part <a onmouseover="LinkshimAsyncLin.swap()> i
want to get also all remain tags and text to the end point
Note :
My friends, I know that using regex with html tag is very bad practice and
i already have red that alot but i want that for special case
thank in advance :)

Facebook image upload with custom post message
Facebook image upload with custom post message
I am currently building an app which generates a custom image with user's
facebook username on it. The username is being collected by one of the
following methods:
Asking user for his Facebook username and doing a graph search and thus
obtaining his username.
Threw Facebook connect which will authorize user to my website and I can
get what I want (with Permissions: publish_stream,user_photos )
In the end, I let user to post the image to his Facebook wall threw a button:
<a href="imageupload.php?filename="abc" >Post this image to facebook</a>
and content of imageupload.php is:
$appId = 'MY_APP_ID';
$appSecret = 'MY_APP_SECRET';
$return_url = 'MY_HOME_URL';
$fbPermissions = 'publish_stream,user_photos';
include_once("inc/facebook.php"); //include facebook api library
//Call Facebook API
$facebook = new Facebook(array(
'appId' => $appId,
'secret' => $appSecret,
'fileUpload' => true,
'cookie' => true
));
$facebook->setFileUploadSupport(true);
//get user
$fbuser = $facebook->getUser();
$access_token = $facebook->getAccessToken();
//get full image path else logout
if(!empty($_GET['filename'])){ $img = 'uploads/'.$_GET['filename'].'.jpg';}
else{
$loginUrl = $facebook->getLoginUrl(array('scope'=>$fbPermissions,
'return_url'=>$return_url));
header('Location: ' . $loginUrl);
}
//variables we are going to post to facebook
$msg_body = array(
'source' => '@' . realpath($img),
'message' => 'I have created this image at '.$return_url
);
if ($fbuser){ //user is logged in to facebook, post our image
try {
$uploadPhoto = $facebook->api('/me/photos', 'POST', $msg_body );
} catch (FacebookApiException $e) {
echo $e->getMessage(); //output any error
}
}else{
$loginUrl =
$facebook->getLoginUrl(array('scope'=>$fbPermissions,'return_url'=>$return_url));
header('Location: ' . $loginUrl);
}
This successfully post my image to Facebook with a "PREDEFINED MESSAGE". I
know I have authorized user, but wouldn't that be counted in a Black Hat
spamming if you are self generating a message on user's wall without
letting him to post the text if he wanted to.
If so, How can I use some dialog box like Facebook Feed (Which I am not
using BTW because it is not the way to post image I suppose) that can
"ethically" send user's photo with a custom message(if this is considered
ethical) to his/her Facebook's wall?
