fpos_t woffset;
woffset = (rec_no - 1) * sizeof(line_rec);
fsetpos(fp,&woffset);
fwrite(arec,sizeof(line_rec),1,fp);
}On the line... (2 Replies)

I am writing some code to do analysis on the file system (HP-UX 11.11).
I am using stat(..) to get file information. My problem is that the file-size may exceed the data types defined in 'sys/stat.h' & 'sys/types.h' respectively.
Thus file-sizes in the Giga-byte range are not read correctly.... (2 Replies)

MYSQL_INSERT_ID(3) 1 MYSQL_INSERT_ID(3)
mysql_insert_id - Get the ID generated in the last query
SYNOPSIS
Warning
This extension is deprecated as of PHP 5.5.0, and will be removed in the future. Instead, the MySQLi or PDO_MySQL extension should
be used. See also MySQL: choosing an API guide and related FAQ for more information. Alternatives to this function include:
omysqli_insert_id(3)
o PDO::lastInsertId
int mysql_insert_id ([resource $link_identifier = NULL])
DESCRIPTION
Retrieves the ID generated for an AUTO_INCREMENT column by the previous query (usually INSERT).
o $
link_identifier -The MySQL connection. If the link identifier is not specified, the last link opened by mysql_connect(3) is
assumed. If no such link is found, it will try to create one as if mysql_connect(3) was called with no arguments. If no connection
is found or established, an E_WARNING level error is generated.
The ID generated for an AUTO_INCREMENT column by the previous query on success, 0 if the previous query does not generate an AUTO_INCRE-
MENT value, or FALSE if no MySQL connection was established.
Example #1
mysql_insert_id(3) example
<?php
$link = mysql_connect('localhost', 'mysql_user', 'mysql_password');
if (!$link) {
die('Could not connect: ' . mysql_error());
}
mysql_select_db('mydb');
mysql_query("INSERT INTO mytable (product) values ('kossu')");
printf("Last inserted record has id %d
", mysql_insert_id());
?>
Caution
mysql_insert_id(3) will convert the return type of the native MySQL C API function mysql_insert_id() to a type of long (named int in
PHP). If your AUTO_INCREMENT column has a column type of BIGINT (64 bits) the conversion may result in an incorrect value. Instead,
use the internal MySQL SQL function LAST_INSERT_ID() in an SQL query. For more information about PHP's maximum integer values,
please see the integer documentation.
Note
Because mysql_insert_id(3) acts on the last performed query, be sure to call mysql_insert_id(3) immediately after the query that
generates the value.
Note
The value of the MySQL SQL function LAST_INSERT_ID() always contains the most recently generated AUTO_INCREMENT value, and is not
reset between queries.
mysql_query(3), mysql_info(3).
