Arun, i suggest that if you are using this for IPC then , better use pipes.
And if you really want to use fd in another application then
pass the file descriptor to exec after doing a fork.
something like this.
in application_1
ret = fork();
if(ret == 0){
sprintf(buff, "%d", fd_1);
(void)exec(

1. I think application_2 can open the file /proc//fds/

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 o
