Is it possible to use file descriptor after main returns


Hello All,

I want to use the file descriptor opened by application_1 in another application_2, i.e

./application_1 :
main()
{
fd_1 = open( file );
return fd_1;
}

./application_2 fd_1
main()
{
ret = read( fd_1 );
return fd;
}

My concern is once application_1 main returns all open fds will be closed right ?

Thanks in advance .

Thanks,
A.R
