I am having some difficulty understanding the implication of lazy evaluation mixed with DUP=F in a .Fortran call. In qr.qty from base DUP is not used as an argument so defaults to T. I am calling qr.qty with a very large array and would like to set DUP=F in the .Fortran call so that qr.qty would be defined as copied below. Is there some risk that a variable used as the argument in the original

Hello, I'm trying to create my own C code for use within R. While optimizing the code I've noticed that even while only using pointers to get my data to C the time needed still depends on data (vector) size. To test this, I've created an empty C function to which I've send vectors containing various sizes of elements. The time needed for each call is measured and plotted. I would

Hello, today I wanted to remove one drive from raid1, and people at #btrfs advised me to use ''-dconvert=single'' before ''btrfs device delete''. I thought of adding ''-mconvert=dup'' too, but the kernel does not let me do that. It looks like ''dup'' is disallowed for an array of multiple devices. So, to go back to a single-drive

Hello all, My scripts, which read stdout from ssh, weren't seeing EOF from the remote session.? It was being sent, but lost.? I tracked it down to the following code, in ssh.c, at ssh_session2_open: ??????? if (stdin_null_flag) { ??????????????? in = open(_PATH_DEVNULL, O_RDONLY); ??????? } else { ??????????????? in = dup(STDIN_FILENO); ??????? } ??????? out = dup(STDOUT_FILENO);

In some tests I am getting a difference in the 7th or 8th significant digit depending on whether I set DUP=T or DUP=F in the .Fortran call below. While this is not a huge error it is bigger than I would expect and may be a symptom of another problem. Any comments or suggestions? (R1.2.2 on Solaris.)

I've been using ssh without it duping stdout and stderr, and had no problems.? I think this change should be made to the master source. WHAT IS THE PROBLEM WITH SSH RIGHT NOW? It duplicates FILENO_STDOUT and FILENO_STDERR, thus there are two descriptors for each of these files.? When the remote program closes its stdout or stderr, the remote sshd sends the appropriate message to the local

That''s weird. Line 296 is just a call to FormatMessage(). Folks on the mailing list - could this be a wide character issue? Buffer too small maybe?

nouveau screens are reused for the same device node. However in the scenario where we create screen 1, screen 2, and then delete screen 1, the surrounding code might also close the original device node. To protect against this, dup the fd and use the dup'd fd in the nouveau_device. Also tell the nouveau_device that it is the owner of the fd so that it will be closed on destruction. Also make

Would that really be useful?? Output from Ill-behaved libraries, written fd 1, already go to the same place.? Don't forget, dup does not create a new file, it creates a duplicate

I have a huge matrix on which I need to do a simple (elementwise) transformation. Two of these matrices cannot fit in the memory, so I cannot do this in R. I thought of writing some C code to do this and calling it using .C with DUP=FALSE. All I need is a simple for loop that replaces elements with their new value, something like void transform(double *a, int *lengtha) { int i; for (i=0;

Hey, I am hoping that some one on this list may be able to help me. I started investigate the possibility of forking a process, the child then attach to a pty, dup std[in|out] to the pty, then exec the ssh client. For some reason, the ssh client still prompted straight to stdin and stdout rather than through the pty that I created. There seem to be a few issues with this. Can someone tell

Hello List, I'm running a ping command to monitor our connection to the Internet. Around yesterday, I was getting a lot of (DUP!) text on the replies. Would anyone know what that means? -- Stand before it and there is no beginning. Follow it and there is no end. Stay with the ancient Tao, Move with the present.

Hi Everyone, I have a piece of C code that uses R_alloc, and so I set DUP=TRUE in the call using ".C". As I understand it this takes a copy of each object passed to my function. If these objects are large then this could be expensive. My question is, if I rewrote the code to use .Call, would I avoid this duplication by using the objects themselves (they are not modified in the code)

I am getting this error on a Win98SE pc, but not on WinNT4 or Linux Redhat 7.1 or 7.2. Failed to dup/close : The descriptor is a file, not a socket The command I used was rsync -e ssh gas.exe 10.105.50.180:src/ It works like I said on NT4 and from my Linux pc. I have cygwin installed on the win98 and NT. Rsync is version 2.4.6 Is it just because Win9x SU**s? Also where can I get a list of
