Your problem is not "buffer size". If you are using a command which reads one line at a time, it will read even long lines, but if the input is more than one line, it will only read the first line.
Let's rephrase this problem. How do you know when something is more than one line? Because the next line is then not a date stamp. So you can create a simple parser for this format, which recognizes everything up to the next date stamp as one input record.
This is probably best done with a scripting language such as awk or Perl or Python, but just for the sake of argument, here's a quick and dirty solution in shell script:
Hi...
I am trying to read a binary data that have different types of messages of different lengths. I am using fread() but this functions needs the size and count to read the buffer from the file. I think this may cause that the buffer overlaps other messages.

When I checked with top command, I found tht my buffers are always 137M, which means that they are sort of overloaded. My Inactive memory is 520M. Is it possible to increaase the buffer size and what would be the command for that? (0 Replies)
The "top" command shows that my buffer size is always at 137M, which I think has reached to the maximum. However, Ido have lots of Inative memory? Is it possible to increae the buffer size? and what is the command for that? Further, this is the buffer for writing to the hard disk? (3 Replies)
Its difficult to explain what I am exactly looking for, so let me try with an example..

Hi Group,
I am struggling to increase buffer size of expect,
sometimes after increasing the buffer size, expect captures all my expected output, sometimes not, :-(
I tried
match_max 700000
set expect_out(buffer) {}
Could anybody guide me for any solution.

Hi,
Can I find size of the file from size of the buffer written?
nbECRITS = fwrite(strstr(data->buffer, ";") + 1, sizeof(char), (data->buffsize) - LEN_NOM_FIC, fic_sortie);
Thank You :) (1 Reply)
Hello,
I would like to increase the size of my buffer in my xterm window. My shell is bash and my home directory is auto mounted. I'm on Solaris 10, RHEL 5 and SLES 11 servers. Do you know where I can do this? (4 Replies)

DESCRIPTION
Procedural style
DateTime date_create NULL ([string $time = "now"], [DateTimeZone $timezone])
Returns new DateTime object.
PARAMETERS
o $time
-A date/time string. Valid formats are explained in Date and Time Formats. Enter NULL here to obtain the current time when using
the $timezone parameter.
o $timezone
- A DateTimeZone object representing the timezone of $time. If $timezone is omitted, the current timezone will be used.

EXAMPLES
Example #1
DateTime.__construct(3) example
Object oriented style
<?php
try {
$date = new DateTime('2000-01-01');
} catch (Exception $e) {
echo $e->getMessage();
exit(1);
}
echo $date->format('Y-m-d');
?>
Procedural style
<?php
$date = date_create('2000-01-01');
if (!$date) {
$e = date_get_last_errors();
foreach ($e['errors'] as $error) {
echo "$error
";
}
exit(1);
}
echo date_format($date, 'Y-m-d');
?>
The above examples will output:
2000-01-01
Example #2
Intricacies of DateTime.__construct(3)
<?php
// Specified date/time in your computer's time zone.
$date = new DateTime('2000-01-01');
echo $date->format('Y-m-d H:i:sP') . "
";
// Specified date/time in the specified time zone.
$date = new DateTime('2000-01-01', new DateTimeZone('Pacific/Nauru'));
echo $date->format('Y-m-d H:i:sP') . "
";
// Current date/time in your computer's time zone.
$date = new DateTime();
echo $date->format('Y-m-d H:i:sP') . "
";
// Current date/time in the specified time zone.
$date = new DateTime(null, new DateTimeZone('Pacific/Nauru'));
echo $date->format('Y-m-d H:i:sP') . "
";
// Using a UNIX timestamp. Notice the result is in the UTC time zone.
$date = new DateTime('@946684800');
echo $date->format('Y-m-d H:i:sP') . "
";
// Non-existent values roll over.
$date = new DateTime('2000-02-30');
echo $date->format('Y-m-d H:i:sP') . "
";
?>
The above example will output something similar to:
2000-01-01 00:00:00-05:00
2000-01-01 00:00:00+12:00
2010-04-24 10:24:16-04:00
2010-04-25 02:24:16+12:00
2000-01-01 00:00:00+00:00
2000-03-01 00:00:00-05:00
