The C function getsockopt lets you get the error codes with the option SO_ERROR . The possible error numbers are defined in the global errno.h . The relevant values are:

The @ operator suppresses error messages.
A usual example is:
<?php
$v = @$a['non-existing-key'];
?>
which suppresses the "undefined index" PHP notice.
Another example is:
<?php
@include('non_existent_file');
?>
In this case, @ not only suppresses error messages for non-existing file, it also suppresses any error messages coming from the included file when it does exist.
Create file test.php :
<?php
@include('test.inc');
?>
Create test.inc :
<?php
<?php
garbage
?>
The "undefined constant" PHP notice message is suppressed by @ .

You get this error message when you try to install an Android APK. Most likely, the APK you are trying to install declared sharedUserId , but there's an existing package with the same sharedUserId , which was signed with a different key than the package being installed.

Current line number for the last filehandle accessed. $/ The input record separator, newline by default. $| If set to nonzero, forces a flush right away and after every write or print on the currently selected output channel. Default is 0 (regardless of whether the channel is really buffered by the system or not; $| tells you only whether you've asked Perl explicitly to flush after...
