Send SMS through a c program

June 2, 2010 in C/C++

Ya! You can! You can send an sms from your computer to any mobile using 3 lines of codings in c program!
Dont beleave?? Okay lets have a try…

First you should have gnokii package installed in your computer. Gnokii is a library for written in c to communicate with mobile phones from your computer. I tested this only on my ubuntu 9.04 so I don what windows users should do here.

Okay now connect your mobile phone with your computer with a data cable. This can be also done using mobile to pc blutooth connection! But this requires little more configurations with gnokii. Just forget it now.

Now open a note pad and write these c code below

#include <sys/types.h>
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
int main(int argc, char **argv)
{
    FILE *file = popen("/usr/bin/gnokii --sendsms 880191xxxxxxx", "w");
    fwrite("HURRAY MSG IS GOING WITH C CODES!!", 1, 5, file);
    pclose(file);
    return 0;
}

Didnt you understand? This is actually… umm
Nothing…

This method is called pipelining. Actually gnokii is doing all that in background. If you open the terminal and enter this command “/usr/bin/gnokii –sendsms 880191xxxxxxx|HURRAY MSG IS GOING WITH C CODES!!” This would also work. Coz here “|” is causing pipelining between terminal standard input and gnkoiii process.
However,

here the c function popen is calling the process just as like a file. So that we can send command to that process just like an file write operation.

And dont try this too much…
Otherwise you would be out of your mobile balance soon…
