Looking at this code
I assume that your problem is that the SIGKILL is being triggered irrespective of whether the character at offset 20 is "Z' or not.
Is 'str' declared as a char or an int?
Also note that if fopen(), fseek() or fgetc() fail the if statement will still be executed with str probably set to some unknown/random value and hence SIGKILL will be triggered. You need to add error checking to avoid this scenario.
Hi! Experts,
Is there anyway to incerase the priority of a process which is already started and running??.. I think nice can used for increase priority when we start the process..
But donno how to do when its already running..
Any help would be apreciated..

Hi All,
Is this correct on DNS searching?
(1st priority) /etc/hosts
(2nd p.) /etc/resolv.conf
Are there more things that I didn't know?
Thank you for any comments you may add. (5 Replies)
Hi,
I can't find the priority in my logs, which under the catalogue of /var/log/lmessages.
For example, if the log below occur on my machine, there is no <30>. What should I do if I want to see <30> .

Good afternoon
I need to KILL a process in a single command sentence, for example:
kill -9 `ps -aef | grep 'CAL255.4ge' | grep -v grep | awk '{print $2}'`
That sentence Kills the process ID corresponding to the program CAL255.4ge.
However it is possible that the same program... (6 Replies)

fseek
FSEEK(3) 1 FSEEK(3)fseek - Seeks on a file pointerSYNOPSIS
int fseek (resource $handle, int $offset, [int $whence = SEEK_SET])
DESCRIPTION
Sets the file position indicator for the file referenced by $handle. The new position, measured in bytes from the beginning of the file,
is obtained by adding $offset to the position specified by $whence.
In general, it is allowed to seek past the end-of-file; if data is then written, reads in any unwritten region between the end-of-file and
the sought position will yield bytes with value 0. However, certain streams may not support this behavior, especially when they have an
underlying fixed size storage.
PARAMETERS
o $handle
-A file system pointer resource that is typically created using fopen(3).
o $offset
- The offset. To move to a position before the end-of-file, you need to pass a negative value in $offset and set $whence to
SEEK_END.
o $whence
-$whence values are:
o SEEK_SET - Set position equal to $offset bytes.
o SEEK_CUR - Set position to current location plus $offset.
o SEEK_END - Set position to end-of-file plus $offset.
RETURN VALUES
Upon success, returns 0; otherwise, returns -1.
EXAMPLES
Example #1
fseek(3) example
<?php
$fp = fopen('somefile.txt', 'r');
// read some data
$data = fgets($fp, 4096);
// move back to the beginning of the file
// same as rewind($fp);
fseek($fp, 0);
?>
NOTES
Note
If you have opened the file in append ( a or a+) mode, any data you write to the file will always be appended, regardless of the
file position, and the result of calling fseek(3) will be undefined.
Note
Not all streams support seeking. For those that do not support seeking, forward seeking from the current position is accomplished
by reading and discarding data; other forms of seeking will fail.
