Incidentally, this should not be 1, since normal packet loss could cause one
packet to be dropped, and this would not necessarily be indicitive of any
unusual behavior.  Perhaps 5 or so would be a good value, and if none come
back, then there is a problem.

The secret is popen.  Use it like this:

FILE *mail;

mail = popen("/usr/sbin/sendmail -t", "w");
/* check that mail is not null! */

/* Now, send headers... */

fprintf(mail, "To: recipient@xxxxxxxxxxxxx\n");
fprintf(mail, "Subject: Something's crashed again\n");

/* Send a blank line to signify end of headers. */

fprintf(mail, "\n");

/* Send the body of the message. */

fprintf(mail, "I can't ping that machine.\n");

/* Send it off. */

fclose(mail);
