I work on a code base which is mostly C with a little C++, and is mostly built with gcc but occasionally it needs to be built with MSVC. Microsoft's C compiler is still pretty much C89 with a few minor extensions, and it still doesn't support mixed code and variable definitions à la C++/C99. So I need to find a way to prevent developers ...
Hello everyone. My problem is that I need to parse an HTML document chunk by chunk and add a comment in the head element of the document. I am using C and I found that libxml2 is the best library out there for this purpose. As I am receiving only chunks of data at a time I thought using a SAX parser would be a better option. Howeve...

I am using GCC + the terminal to make an array of prime numbers. I once asked on #[email protected], but I still don't understand: An int can store values on 32 bits (so a total of 2^32 unique values), but can't an array have more than 2^24 values ? I'm not sure, but is http://stackoverflow.com/questions/2318278/why-24-bits-registers...
struct inode_operations ext3_dir_inode_operations = { .create = ext3_create, .lookup = ext3_lookup, } This struct is assign to inode structure and further to file system operation structure. My question is what is this flag .create? Do we do the assignment in the structure itself? Or is it some other ver...
I am trying to get the size of PNG image (Without storing into file). I am using this code as reference. When calling GetDIBits(), size of image would get updated into bi.biSizeImage. Everything works fine when bi.biCompression is BI_RGB. Then I have changed the compression mode from BI_RGB to BI_PNG; GetDIBits() started to fail. Please ...
I've been annoyed lately by the fact that PyDev doesn't information about classes and function when it code completes wxPython code. Can anybody tell me FOSS IDE's or extensions that offer code information (function params, returns etc.) when it code completes for C/C++ and Python. I am a fan of CodeLite, Eclipse CDT and CodeBlocks in ...

Every othe...

Hi, I tried to read the /proc/modules using standard c functions: FILE *pfile; int sz; pfile = fopen( "/proc/modules", "r" ); fseek( pfile, 0, SEEK_END ); sz = ftell( pfile ); rewind( ftell ); But my problem is ftell give me 0 value. So I can't read the contents of the file since I have a zero length. Is there another way that I can ...
A long time ago I used to program in C for school. I remember something that I really hated about C: unassigned pointers do not point to NULL. I asked many people including teachers why in the world would they make the default behavior of an unassigned pointer not point to NULL as it seems far more dangerous for it to be unpredictable. ...

Using fprintf, what is the format-string to output two digits after a decimal separator? float number = 3.0; fprintf(pFile, "%10.02f", number); This always outputs 3 instead of 3.00 How do I fill up the digits after decimal separator with zeros? I want 3.00 written in the output file. ...

What are some good do-s and don't-s for floating point arithmetic (IEEE754 in case there's confusion) to ensure good numerical stability and high accuracy in your results? I know a few like don't subtract quantities of similar magnitude, but I'm curious what other good rules are out there. ...
I have a char* name which is a string representation of the short I want, such as "15" and need to output this as unsigned short unitId to a binary file. This cast must also be cross-platform compatible. Is this the correct cast: unitId = unsigned short(temp); Please note that I am at an beginner level in understanding binary. ...
