Debian Programming :: C++ Function Call For Manual SSD-TRIM Commands

Jul 25, 2015

I'm looking for a way to launch "TRIM" commands to a SSD drive myself, from a c++ code I'm going to write, for flash erasing an SSD drive (and not to wait for others things that "should do it automatically in some circumstances if this or this, this and this have been enabled and [..]" but will never tell me if it worked or not

I know there is thousands of complicated ways to test and check if it worked, and also software that needs money to do so, that's why I just want to call myself the TRIM functions and read the return value (like true or false) in order to know if it worked !

Where I can find the c++ call that could permit me to do so ? I heard about the GLibC that gives a way to access every user space function related to Linux Kernel (poll, select and others) as standard c++ functions, I suppose that, if there is a way, it will be on the GLibC but how to find it ?

And the php mysql_connect() function works as tested in this .php file

Code:

Using the script

And the mysql.php file which issues the error is like this:

Code:

I have also tried editing the mysql_connect function to be something like the test script i mentioned above, but still get the same error.

I have installed LAMP server using the apt-get (installed following packages: apache2 php5 libapache2-mod-php5 mysql-server mysql-client php5-mysql phpmyadmin) everything so far works great.

What i have noticed, that even though mysql shows up in phpinfo, it doesn't show up as a module listed in 'php -m'

Programming :: PHP Fatal Error - Call To Undefined Function Mysql_connect()

Am getting errors about "mysql_connect()" for the following code:

Have compiled PHP with MySQL support using the following:

Thought PHP 5.3 has a built-in replacement called mysqlnd, and there's no need to install "php-mysql" RPM.

However, according to the following site this is still required: [url]

Give me an idea whether I really have to install php-mysql RPM in order to use mysql_connect() for PHP?

General :: System Call To Know Files And Directories In PWD

Mar 3, 2010

I am searching for any system call similar to "ls" command we use in shell. My requirement is knowing the files and directories in curent working directory and process them based on there type. Here as of now I spawn another procees with system command like system
("sh ls -l | grep ^d | awk '{print $9}'").

Instead of this I want to use any system command where I can capture this information directly into my local character buffer. My opinion is that system calls will not spawn another process as a result less time it takes, another reason is once I use the system command again I need to capture the information to a local file then again read it into local buffer. I want to avoid the file manipulation here.

I am trying to connect to my mysql database using php but I am getting the error "Fatal error: Call to undefined function mysql_connect()".

I checked phpinfo() and there is no reference to MySQL. I believe this means that my install of PHP doesn't support MySQL. Do I need to uninstall and reinstall with a version of PHP with MySQL support? If so how should I do this and how do I get a version of PHP that supports MySQL?

General :: DMESG Does Not Display The Kernel Driver Function PRINTK Message

Apr 7, 2010

Kernel driver function was called via ioctl and returned success, but when I checked the kernel display buffer with dmesg the printk message was not there. Then when you do lsmod, the driver you were calling showed "used by zero". So it seems like the kernel driver was not accessed. In the kernel driver, I had many printk statements, but nothing printed in the buffer. if the driver get accessed and what could cause this?

General :: Reboot(LINUX_REBOOT_CMD_RESTART) - Lock Up The System And Does Not Return From The Call?

Jul 8, 2011

I am running an embedded Linux Release 2.4.19-uc0.

I have code in several places that calls

reboot(LINUX_REBOOT_CMD_RESTART)

successfully. I need to put it into a new place in a application running on the system. When I do, it seems to just lock up the system and does not return from the call nor leave me able to Telnet in or Ping or anything. I've tried puttingtrace code in to write info out to a file, but that too is not working (as it never returns from the reboot() call.I don't get any error from reboot(), it just does not return and does not appear to restart the system.
