This works fine when typed at the Unix prompt.

echo "This is body" | mail -s "This is subject" "id@domain.com")


But this does not put the Subject Line in the e-mail.

int MainProcess()
{
char cmd[500];
sprintf( cmd, "echo %s | mail -s %s %s\n","This is body","Subject Line","id@domain.com");
if (system ( cmd ) !=0 )
{
fprintf(stderr, "error calling system");
}
return SUCCESS;
}

Code:

sprintf( cmd, "echo '%s' | mail -s '%s' %s\n","This is body","Subject Line","id@domain.com");

You have to force the shell to delimit the body and subject using single quotes
