I have been going through a few published papers which details algorithms and data structures which can be used for implementation of a thread library. I searched online to view any existing implementation of the same, and I could only find LFThreads(only its documentation, not its source code). Have any of you worked on/used a lock-fre...
I'm trying to compile an open source project on windows under mingw/msys. The makefile contains (among others) this line @${MAKE} --no-print-directory -C . -f physfs.make physfs.make contains (among others) these lines: ifndef CC CC = gcc endif when I ran make I get the following error: Creating obj/Debug/physfs physfs.c make[1...

I have made a toolchain using this script: http://gist.github.com/403608 (more or less modified to get it to work) Everything is installed and now when I try to compile using it I get an error when I ./configure it says that my C compiler cannot create exeicutables. I'm thinking that my compiler just doesn't know where to look for all ...
The code below is me trying to instantiate a 2d array, and it instantiating incorrectly: THE CODE: FILE* kernalFile = fopen(argv[1], "r"); int rKernalSize; fscanf(kernalFile, "%d", &rKernalSize); unsigned int rKernal[rKernalSize][rKernalSize]; Data froma break point right after that code is ran: rKernalSize VALUES: N...
I'm trying to read a binary file into a C# struct. The file was created from C and the following code creates 2 bytes out of the 50+ byte rows. unsigned short nDayTimeBitStuffed = atoi( LPCTSTR( strInput) ); unsigned short nDayOfYear = (0x01FF & nDayTimeBitStuffed); unsigned short nTimeOfDay = (0x01F & (nDayTimeBitStuff...
I'm trying to print the values in a struct timeval variable as follows: int main() { struct timeval *cur; do_gettimeofday(cur); printf("Here is the time of day: %ld %ld", cur.tv_sec, cur.tv_usec); return 0; } I keep getting this error: request for member 'tv_sec' in something not a structure or union...
Suppose I have an ELF binary that's dynamic linked, and I want to override/redirect certain library calls. I know I can do this with LD_PRELOAD, but I want a solution that's permanent in the binary, independent of the environment, and that works for setuid/setgid binaries, none of which LD_PRELOAD can achieve. What I'd like to do is add...
Hello, I'm building an Authentication Package for Windows and I'm now just trying to make a skeleton for the package that I'm going to build. The Package at some point in time will need to call MSV1_0 but the workflow of my authentication is forbidding me from implementing it as a SubAuthentication Package for MSV1_0. Now, please exa...

Assuming I have a piece of code similar to this: SOMESTRUCTURE *info; info = malloc(sizeof(SOMESTRUCTURE)); while(something...) { info->mini[0] = malloc(sizeof(SOMESTRUCTURE *)); // It's a structure inside the same structure while(something...) { info->mini[x]->name = malloc(sizeof(char *)*strlen(name)); ...
I understand there is a SecureZeroMemory function in C. The function implementation is defined in <WinnNT.h> as RtlSecureZeroMemory function. QNS: How can SecureZeroMemory be used in Delphi? Did Delphi release a library that contains that function? I'm using Delphi 7. Windows.pas only has ZeroMemory but not SecureZeroMemory. ...
I have been spending some time in debugging a programme which gives segmentation fault. The bug is quite indeterministic and intermittent, which is annoying. I narrowed it down to the calling of strtok. I suspect that it is the calling of strtok to split string in two different threads that causes the segmentation fault. Can I call strto...

I have few doubts regarding how windows manages a .dll's memory. when .dll's are loaded into the host process, how is the memory managed? Does .dll get access to the entire memory available to the host process or just a portion of it? i.e is there a limitation when memory is allocated by a function inside the .dll? Will STL classes li...

I am debugging a C program (GCC and GDB in Linux and Visual Studio in Windows) that gives different results on two different architectures.

Variable A changes from 34 to 23 f...
Hello, I know the program name is passed as the first argument, and next simple example will print it to the standard output : #include <iostream> int main ( int argc, char *argv[] ) { std::cout<<argv[0]<<std::endl; } Is there a function to get the program name? EDIT I am starting the program from the shell, and the above code wi...
I have a 2d array matrix[10][10] that I'd like to inspect at debug time. I understand that I can do this in GDB using p *matrix@10 But it outputs this in one line, making it difficult to read. Is there a way to have this output formatted in any way, lets say as a matrix? ...
