Automatically removing unneeded #include statements
Possible Duplicates: C/C++: Detecting superfluous #includes? How should I detect unnecessary #include files in a large C++ project? Hi, I've been following numerous discussions about how to reduce the build time for C/C++ projects. Usually, a good optimization is to get rid of #include statements by using forward declaration...
strncpy and using sizeof to copy maximum characters
Hello, I am using the code below char call[64] = {'\0'} /* clean buffer */ strncpy(call, info.called, sizeof(call)); I always use the sizeof for the destination for protecting a overflow, incase source is greater than the destination. This way I can prevent a buffer overflow as it will only copy as much as the destination can handle....

Reading part of a file in C using fread() and fseek()
I'm trying to read a file into a buffer in blocks of size BLOCK_SIZE (currently equal to 1000 unsigned chars). My code first finds the number of blocks it will have to read in order to read the entire file (usually 2-4), then iterates through a for loop reading the file (ignore the "+17+filenamesize" stuff, that is all needed for later i...

How to create project dependencies in netbeans (c/c++ plugin)
As I work on a c++ application, I realize I am making a lot of classes and functions that could be used in other projects. So I'd like to put all this code in a separate net beans project that can be "included" into other projects.

Dynamic modules with DLLs on Windows
I'm writing an application in C that can be extended at runtime by means of modules / shared objects / DLLs. Those modules may use the API of the existing program but may also provide new functions for use in later loaded modules, so there is the possibility for modules to have dependencies on each other. My current approach under Linux...

Alternative to Complex.h in Visual Studio
I know very little about VS, and was surprised when my linux code did not compile on windows. The problem seams from the lack of <complex.h> in VS. My question is this: do people re-implement in their Windows applications, or is there a public domain version. ...
