Programming :: Tty Is Closed Without Calling Close(?)

Feb 17, 2011

I have found a weird behaviour on a linux application. A tty seems to get closed without calling close. The program is (very simplified) as follows:

Process 1:

Thread 1:
usleep(a while)

I have spent quite a lot of time on this problem. It seems like the file is sometimes closed when reaching config(fd), but removing the usleep(a while) seems to remove the problem.

Programming :: Calling Fortran 95 Code In C?

Apr 15, 2009

I'm trying to call some Fortran 95 code in C, but I'm having problems with integers not having the same value in C as in Fortran, and changing values upon each run of the program. I think it has to do with the integer type, but I don't know how to fix it. I'm running Gentoo x86. Here are the files I've got:



#include <stdio.h>
extern int qux_();
main() {

Programming :: Calling A System Command In Perl?

May 20, 2010

I'm trying to call a system command in perl and am having an issue with it.

Here's an example of a command i'd like to call: Code: sed -i '4 c192.168.1.4' hosts this is the section in my perl script where I create the variable and call it: Code: $doit = `sed -i '$line c$ip $host hosts'`system($doit); The $line, $ip, and $host variables are working fine becasue I can replace that section with "prints" and they come out fine. I imagine the problem is where I am creating the $doit variable.

Programming :: Calling Routines In Fortran Modules From C++?

Jan 21, 2011

I want to call a subroutine in Fortran 90 from a c++ code. I can do it, when the fortran code have no module. But i need to call the subroutine in a fortran code that have an module. I have a simple program that shows my problem. The Fortran code is:

Code: !add2.f90
Module add2
Implicit none


collect2: ld returned 1 exit status I Dont know where is the problem. Maybe it is in the call of the function. I found that the syntax have this form: extern void __namemodule__NMOD_namesubrutine(arg)

Programming :: C++ - Calling Functions From Other Files And Headers?

Apr 11, 2011

I feel like there should be a cleaner way of doing this. I have one file, for example "a.cpp", calling a function from another file, "b.cpp". Currently I have it set up so that header for "b", "b.h", has the declaration of its functions. And then I'm just including "b.h" in "a.cpp". Do I have to include the "b" header file in "a" to be able to call a function from "b"? Or is there a better way I could be doing this? Like doing something different at compile?

Programming :: Calling Gcc From Executable File / (makefile)

Oct 4, 2010

I am trying to use a software package written in ANSI C. It has a makefile which has to be executed first.

As soon as I execute it I get messages like: line i: command not found.

Commands for which I am getting errors :

CC = /usr/bin/gcc
GCCFLAGS = -c -Wall

My gcc compiler is located in the above directory only. In ROOTDIR also I tried giving the path in which all the required files & folders are present but still I get the command not found error in all the lines.

Programming :: Calling Kernel Functions From Userspace?

Feb 5, 2010

I'm trying to call some kernel functions from userspace, but I'm not sure if I'm doing it right. The functions control a pulse width modulator on an embedded platform. To pick one at random, the function:

struct pwm_device *pwm_request(int pwm_id, const char *label);
is defined in linux/pwm.h, and the implementation uses the macro EXPORT_SYMBOL(pwm_request), so I should be able to call this from user-space... right?

Anyway, I've got linux/pwm.h to #include in my source so the compiler knows what it's doing, but what do I link against? The only place in by kernel build tree where I can see a symbol pwm_request defined is in object files like vmlinux.o, built-in.o in the directory, etc. which I don't think I should be linking against.

Programming :: Calling Multiple Files In FORTRAN90

Oct 29, 2010

I have written FORTRAN code to calculate density profile. This code will open two files ( topology and x,y,z trajectory). The trajectory file contains XYZ data coordinates for multiple frames (about 20 or 100 frames for instance). One frame contains 20736 data.

Previously this code was written to open ONLY one input XYZ data file and do the calculation and would dump the results in separate file and it was running without problem. Recently my data file get bigger in size, so I decided to break the single XYZ data file into few small parts.

Now I have modified the code so that it calls the parts of the XYZ data files ( eg: maltoTHERMO_10Frames.traj, maltoTHERMO_20Frames.traj,... and so on) and do the calculation and dump the results in the same result output file. I have tested this code just with openning the XYZ coordinates and printing into another file to see wheather it collecting the data sequently and it was working fine.

This code supposedly read the x coordinate data and calculate distance and put a count accoding the criteria in the approperiate bins. But when I let the code to do the calculation it stop and shows error. (I have indicated as !** in the code). If I enable this line, it shows error but if I disable this line, than the code do collect only the XYZ coordinates.

The code is as below:


module all_parameter
integer,parameter :: MAXATOM=20736!CHANGE
integer,parameter :: midwater=1500
integer,parameter :: TOTALFRAMES=20

Programming :: Scalar Arguments - Changes Reflected In Calling Program

Dec 3, 2010

(For function arguments): Scalar arguments are passed by value, which means that a copy of the argument is made for processing in the function, and changes to the argument in the function won't be reflected back to the calling program. Objects though, are passed by reference: any changes to them in the function are reflected in the calling program. What sense does this make? Why have they done this?

Programming :: Calling Umount2() Unmounts Volume But Df Entry Still Visible?

Nov 14, 2010

This is an odd one. I have a C program that calls umount to unmount a volume. A simplified case looks like this:

Code: int main()
int rc = umount2("/v0", MNT_FORCE);
if (rc != 0)
printf("Unable to unmount volume /v0, err='%s'", strerror(errno));

I also discovered the reverse effect with calling mount() in code. When I make a call like Code: mount(drive, volume, "xfs", MS_NOATIME, NULL); the indicated drive is mounted since I can access the files as expected, but df doesn't show the drive has been mounted.

Why is my C code behaving this way? What do the mount/umount commands do when run from the command line that I'm not doing in my C code?

Programming :: Fork() Copies The Address Space Of The Calling Process?

May 13, 2010

I know that fork() copies the address space of the calling process. Say, however, i have a linked list allocated. Will the list be copied over to the child process's space? If so, i would have to free them in the child process as well as the parent process, correct? Or will the variables be copied but not be pointing to any valid address? Or would it just kind of not do anything?example:

struct ll_ex {
struct ll_ex * next;
