I have a library written in C and I have 2 applications written in C++ and C. This library is a communication library, so one of the API calls looks like this: int source_send( source_t* source, const char* data ); In the C app the code does something like this: source_t* source = source_create(); for( int i = 0; i < count; ++i ) ...

Is it possible to distribute only the bytecode version (.pyc file) of a Python script instead of the original .py file? My app embeds the Python interpreter and calls PyImport_Import to load a script. How can I tell it to look for a .pyc file and import that? ...
Anyone here familiar with the AGNAS library? I've got SampleCoreTemp mostly doing what I want but it spikes CPU usage too much when it's active and I don't want to have to enable/disable constantly if I can find a way to adjust the polling rate instead. ...
I'm doing some prototyping work in C, and I want to compare how long a program takes to complete with various small modifications. I've been using clock; from K&R: clock returns the processor time used by the program since the beginning of execution, or -1 if unavailable. This seems sensible to me, and has been giving results whic...
What's wrong with the following implementation of a binary search tree (BST)? I have been told that it is better to use pointer to a pointer to struct node as an argument in insert function. struct node { int key_value; struct node* left; struct node* right; }; insert(int key, struct node *leaf) { if( leaf == 0 ) { leaf...
I wish to give an effect to images, where the resultant image would appear as if it is painted on a rough cemented background, and the cemented background customizes itself near the edges to highlight them... Please help me in writing an algorithm to generate such an effect. The first image is the original image and the second image i...
I see that Visual Studio 2008 and later now start off a new solution with the Character Set set to Unicode.

i have a closed source program that prints output to standard output. i need to parse the output. so i redirect the output to a fifo (from which i can read in the parent process that forks and execs the binary) using dup2 and then exec the program. the problem is that the fprintf calls in the file become buffered because it is now writin...

Hi, I have a big app using many static libs, which is platform independant and deployed under Windows and Linux. All static libs and the main() itself are compiled with two defines: -DVERSION=1.0.0 -DBUILD_DATE=00.00.0000 These defines are used by macros inside each static lib and inside the main to store the current lib version ins...
A function returns an aray of integers and I want it to pass to another function which searches for some pattern. But the second function expects a string. Example: int IArray = {1, 2, 3}; // should be coverted into "123" Is there a direct function available? If not, how do I convert the array of integers into a string? ...
