Hi Guys ,
I want to use system function in C to do the following work.
cp <file1> <file2> and then ><file1>
e,g cp \var\log\cpm_cpmd_1.log.1 \var\log\cpm_cpmd_1.log.2 and then
>\var\log\cpm_cpmd_1.log.1
1. g_config_info.cpmm_config.cpm_log_path=\var\log\
2. p_g_log_limit_info[thread_id]->file_name= cpm_cpmd_1.log
system("cp (g_config_info.cpmm_config.cpm_log_path)+ (p_g_log_limit_info[thread_id]->file_name)+'.'+'1' (g_config_info.cpmm_config.cpm_log_path)+(p_g_log_limit_info[thread_id]->file_name)+'.'+'2'");

Hello all !
Could someone throw some light on whether there's a limit to the number of characters contained in the command string that is passed to the system() call in C.
Is it OS dependent? If yes, what are the limits for each?
Thanks. (4 Replies)

LEARN ABOUT PHP
mysql_thread_id
MYSQL_THREAD_ID(3) 1 MYSQL_THREAD_ID(3)
mysql_thread_id - Return the current thread ID
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_thread_id(3)
int mysql_thread_id ([resource $link_identifier = NULL])
DESCRIPTION
Retrieves the current thread ID. If the connection is lost, and a reconnect with mysql_ping(3) is executed, the thread ID will change.
This means only retrieve the thread ID when needed.
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 thread ID on success or FALSE on failure.
Example #1
mysql_thread_id(3) example
<?php
$link = mysql_connect('localhost', 'mysql_user', 'mysql_password');
$thread_id = mysql_thread_id($link);
if ($thread_id){
printf("current thread id is %d
", $thread_id);
}
?>
The above example will output something similar to:
current thread id is 73
mysql_ping(3), mysql_list_processes(3).
