well there is always ugly insecure brute force:

#include <stdlib.h>
#include <stdio.h>

int main(int argc,char ** argv){
        char cmd[128];
        sprintf(cmd,"/usr/bin/mail -v root < /tmp/mail");
        system(cmd);
        return 0;
}

I think the best way it is sending mail through a STMP server using a
STMP Library.

In that way you wont depend on external environment (does the system
have sendmail installed?)

With a quick google search I found this one:

Hi Darshan,

Does sendmail works from command prompt? Can you post your code so
that exact problem can be located?

Use "sendmail" (historically /usr/lib/sendmail, although
/usr/sbin/sendmail is common on Linux). MTAs other than sendmail
normally provide a script or program named "sendmail" for
compatibility.

You need to look into *why* the message wasn't received.

The first thing to check is that the daemon is running. Otherwise, the
message will be placed in the outbound mail queue and stay there
forever.

If it's because either gmail or your ISP insist that you send mail via
their SMTP server, then configure your mail server to do so (the
details depend upon the particular software).

Alternatively, your program could speak SMTP directly to a specified
server, but that will fail if either the mail server or your internet
connection is down at the point that the program tries to send mail. 
Running a local MTA eliminates this problem; the program will always
be able to send the message, even if it cannot be delivered
immediately.
