Hi Gurus,
There is a ASCII file in which a comma is used as a seperator for the amount field when the amount exceed seven digits: e.g. 0001300,000. Now, this comma needs to be removed from this field, after padding leading zeros (to maintain the ASCII positions) e.g. 00001300000.... (1 Reply)
Hi,
Can someone explain what is byte padding?
For ex:
struct emp{
char s;
int b;
char s1;
int b1;
long b3;
char s3;
}
What will be the size of this structure?
Thanks (6 Replies)

Hi everybody,
I have a question about typesetting. I originally wrote a script for use with ksh and now I am on a system that I cannot modify, and it only has bash.
In the original script I just did typeset -RZ4 variable and it would add the leading zeros. In bash, it doesn't work.

ip2long
IP2LONG(3) 1 IP2LONG(3)ip2long - Converts a string containing an (IPv4) Internet Protocol dotted address into a proper addressSYNOPSIS
int ip2long (string $ip_address)
DESCRIPTION
The function ip2long(3) generates an IPv4 Internet network address from its Internet standard format (dotted string) representation.
ip2long(3) will also work with non-complete IP addresses. Read http://publibn.boul-
der.ibm.com/doc_link/en_US/a_doc_lib/libs/commtrf2/inet_addr.htm for more info.
PARAMETERS
o $ip_address
- A standard format address.
RETURN VALUES
Returns the IPv4 address or FALSE if $ip_address is invalid.
CHANGELOG
+--------+---------------------------------------------------+
|Version | |
| | |
| | Description |
| | |
+--------+---------------------------------------------------+
|5.2.10 | |
| | |
| | Prior to this version, ip2long(3) would some- |
| | times return a valid number even if passed an |
| | value which was not an (IPv4) Internet Protocol |
| | dotted address. |
| | |
+--------+---------------------------------------------------+
EXAMPLES
Example #1
ip2long(3) Example
<?php
$ip = gethostbyname('www.example.com');
$out = "The following URLs are equivalent:<br />
";
$out .= 'http://www.example.com/, http://' . $ip . '/, and http://' . sprintf("%u", ip2long($ip)) . "/<br />
";
echo $out;
?>
Example #2
Displaying an IP address
This second example shows how to print a converted address with the printf(3) function in both PHP 4 and PHP 5:
<?php
$ip = gethostbyname('www.example.com');
$long = ip2long($ip);
if ($long == -1 || $long === FALSE) {
echo 'Invalid IP, please try again';
} else {
echo $ip . "
"; // 192.0.34.166
echo $long . "
"; // -1073732954
printf("%u
", ip2long($ip)); // 3221234342
}
?>
NOTES
Note
Because PHP's integer type is signed, and many IP addresses will result in negative integers on 32-bit architectures, you need to
use the "%u" formatter of sprintf(3) or printf(3) to get the string representation of the unsigned IP address.
Note
ip2long(3) will return FALSE for the IP 255.255.255.255 in PHP 5 <= 5.0.2. It was fixed in PHP 5.0.3 where it returns -1 (same as
PHP 4).
