I've recently updated the coxme package, which calls internal routines from the bdsmatrix package.? (It is in fact mentioned as an example of this in the Extensions manual.) The call connections are a blocks like this, one for each of the 9 called C routines. void bdsmatrix_prod4(int nrow,??? int nblock,?? int *bsize, ??????????????????? double *bmat, double *rmat, ??????????????????? int

Dear List, I'm trying to get diff/removed data and it's offset out. So I write a functions in receive_data. When I run backup, I found there is a weird behavior which I don't understand. i = recv_token(f_in, &data) will receive (i = -1, offset2 = 0) some where in the middle of the transfer procedure. That's to say, it's going to transfer the first data block from sender,

This version fixes three bugs in the 2nd patch of this series that caused kernel BUG when the system was under race. We weren't accounting with t_oustanding_credits correctly, and there were race conditions caused by the fact the I had overlooked the fact that __jbd2_log_wait_for_space() and jbd2_get_transaction() requires j_state_lock to be write locked.

Dear all, We are facing this problem for long, and so ask for your help. We are plotting 2 graphs in a postscript device (left part -layout function-), and the common legend for these graphs on the right part. The legend in the postscript device looks ok: this is color lines with numbers on the right (6 columns) , see the code below: > nblock<-c(1:48) > leg<-paste(c(1:npin),"

You can legally cast a function pointer to another function pointer, where the signatures differ. (It is not legal to cast between data and function pointers.) I would make typedefs for the various signatures, as the casting syntax is more readable then.

Hi, With kernel 2.4.10, when I do $ mkdir foo; cd foo; rmdir ../foo; ls then ls becomes zombie. $ ps xau|grep ls liu 596 0.0 0.0 148 88 ? D 12:03 0:00 ls This does not happen with 2.4.10 on an ext2 filesystem, nor with 2.4.9/ext3. The command cd instead of ls is OK. Distribution is Slackware 8.0 and the kernels are stock ones. Liu

Dear all, We are analysing some survey data and we are not sure if we are using the correct syntax for our design. The population of interest is a set of 4416 polygons with different sizes ranging from 0.003 to 45.6 ha, 7460 ha in total. Each polygon has a binary attribute (presence/absence) and we want to estimate the probability of presence in the population. We used sampling with replacement
