similar to: Calloc : syntax error

Hello, when looking at "Writing R Extensions" with mem-allocation in mind, I wondered, which functions to use to substitute malloc(), calloc(), realloc() and strdup() and free(). It looked like Calloc() or R_Calloc() might be useful for some of my tasks, but when trying to use R_Calloc() for example, I got some error messages which I don't see where they are coming from. Maybe I

Hi all, I have a C code in Linux, it has 7 pointers and compile e run OK, but when I run in R happens problems with calloc function, it returns NULL. ############################################### > int *temp1,*temp2,*temp3,*temp4; temp1 = (int *)calloc(col,sizeof(int)); if(temp1 == NULL){ printf("\n\n No Memory1!"); exit(1); } temp2 = (int *)calloc(col,sizeof(int));

Hi, it looks like a few users of calloc had their arguments backwards. I checked the other users and they seem fine.

Hi All, While debugging: https://bugzilla.redhat.com/show_bug.cgi?id=1008089 I made a apitrace recording of the a single slide transition animation, and since I suspected memory corruption replayed it using ElectrFence + glretrace, this finds a 0 sized array allocation at src/mesa/state_tracker/st_glsl_to_tgsi.cpp: 5565: if (proginfo->Parameters) { t->constants = (struct

I am trying to write a C function to create a vector of integers that can be used by the R calling function. I do not know the size of the vector in the R calling function. (Well, actually, I have an upper limit on the size, but that is so large that R cannot allocate it. What I'm doing in the function is to do a sieving procedure, and the result will be small enough to fit into my

I'm running R 2.10.0 under Mac OS X 10.5.8; however, I don't think this is a Mac-specific problem. I have a very large (158,908 possible sentences, ca. 58 MB) plain text document d which I am trying to tokenize: t <- strapply(d, "\\w+", perl = T). I am encountering the following error: Error in base::gsub(pattern, rs, x, ...) : Calloc could not allocate (-1398215180 of

[sending this to R-devel, since it may be of general interest and could possibly lead to better instructions in the "R-exts" manual] Is this another case where only .Call() or .External() [or a fudge factor] solve my problem?

I've committed the change to use Free instead of free in tcltk.c and sys-std.c (r78652 for R-devel, r78653 for R-patched). We might consider either moving Calloc/Free out of the Windows remapping or moving the remapping into header files so everything seeing our header files uses our calloc/free. Either would be less brittle that the current status. Best, luke On Sun, 7 Jun 2020, peter

That commit was about converting a couple of malloc+memset to calloc, not about replacing messages in other parts.

I would like to retrieve a vector of integers from a call to .C(), but I don't know its length in advance. How do I do this without making an ugly safe guess? My vector is called "sequences". I am passing the argument sequences = integer(0) in the call to .C(), then declaring the corresponding argument as int *sequences in my C code. I tried R_alloc()ing the storage in C and

I'm trying to load Affy Annotation data from an Access database into R using RODBC. This has worked fine for quite some time. The bug seems to be correlated to RODBC versions 1.1-7 and later. Works fine: R 2.2.0 with RODBC 1.1-4; R 2.3.0 or R 2.4.1 with RODBC 1.1-6 Fails: R 2.3.1 with RDOBC 1.1-7; R 2.4.1 with RODC 1.1-7 or 1.1-8 Details ===== This works fine: Version 2.2.0
