Thanks everyone , and yes DOS is an option but not now haha.
Ok jim mcnamara , you are right when you say that i'm not a experience person in real time programs , in fact this is my first time. But I'm a little bit confused , always I though that semaphores , locks and mutexes are usefull only in programs for condition races . How can i use them for realtime programs?
Thanks for the link I'm gonna to read it.
Bye

NAME
mattrib - mtools utility to change DOS file attribute options SYNOPSIS
mattrib [-a | +a] [-h | +h] [-r | +r] [-s | +s] msdosfile [msdosfiles...] The mattrib command sets (+) or clears (-) the attribute options of a DOS file. OPTIONS
Sets or resets the archive bit. Some backup programs use this option to indicate a new file. Sets or resets the hidden-bit. This option hides files from the DOS DIR command. To view these files, use the mdir command. Sets or resets the read-only bit. This option is used to indicate a read-only file. If this bit is set, a file cannot be removed using the DOS DEL command. To remove the file, use the mdel command. Sets or resets the system bit. This option is used by DOS to indicate an operating system file. DESCRIPTION
The mattrib command sets the attribute options of a DOS file using the plus (+) operator, or clears attribute options using the minus (-) operator. DOS pathnames that contain the '/' or '' separator are supported. If you use the '' separator or wildcards, you must enclose file names in quotes to protect them from the shell. The mcd command can be used to establish the device and the current working directory (relative to DOS), otherwise the default is A:. RESTRICTIONS
The DOS version of the attrib command does not support all of the options listed on this reference page. EXIT STATUS
The following exit values are returned: Success. Failure. ENVIRONMENT VARIABLES
