I have a build system tool that is using getcwd() to get the current working directory. That's great, except that sometimes people have spaces in their paths, which isn't supported by the build system. You'd think that you could just make a symbolic link: ln -s "Directory With Spaces" DirectoryWithoutSpaces And then be happy. But u...
Hello, In Python it's easy: x = {} x['USD'] = "Dolars" x['CLP'] = "Pesos" or y = {'lat': 23.678900, 'lng': 121.451928, 'name': "Sin City"} I think most of these kind of problems are solved so where can I get information about dictionaries in C? I don't want to reinvent the wheel. How do I implement a dictionary in C? ...

I'll explain: Let's say I'm interested in replacing the rand() function used by a certain application. So I attach gdb to this process and make it load my custom shared library (which has a customized rand() function): call (int) dlopen("path_to_library/asdf.so") This would place the customized rand() function inside the process' m...
I am not very good at c at all. I have tried to capture the essense of what the C code does in C# using this wikipedia article. However my version is totally different and does not achive the same compression that the C code does. Therefore, I'd like to port the following code from C to C#. However, i do not need it to read/write to file...
Hey guys Lets say I have an int variable n = 8. On most machines this will be a 32 bit value. How can I only get the lower 8 bits (lowest byte) of this in binary? Also how can i access each bit to find out what it is? My question is related to C ...
In Photoshop there is a tool that allows the selection to be "Distorted". This allows easy shadow creation among other things. How could this sort of distortion be applied for a polygon (a bunch of points)? Thanks ...

hey, here's my code #include <stdio.h> #include <string.h> int main() { char *array[10]={}; char* token; token = "testing"; array[0] = "again"; strcat(array[0], token); } why it returns Segmentation fault? I'm a little confused. ...
Whats the best way to send float, double, int16 over serial on Arduino? The Serial.print() only sends values only ascii encoded. But I want to send the values as bytes. Serial.write() accepts byte and bytearrays, but whats the best way to convert the values to bytes? I tried to cast an int16 to an byte*, without luck. I also used memcpy,...
How can I detect one or combination of strokes of keys in ANSI C and/or with Win32 SDK? For example: how can I detect CTRL+ALT+DEL was pressed? Please provide me with some source code or any web-link. Please note that, I am using polling mechanism, not event. I need to do it in win32 console mode. ...

First, I am working on a project that opens an electric door when certain cell phones call the GSM modem's SIM card's number. But, as a starting point I want to send some AT commands to the modem, then from there I can continue. Here is the code I wrote so far: #define CINBUFSIZE 255 #define COUTBUFSIZE 255 #define TIMEOUT 500 char mode...
When moving an application from 32bit to 64bit, where will increased memory usage occur? I understand that pointers will double in size, I suspect that the chars in a string are 'bunched' to use memory more efficiently (so will not use much more memory). Where else would memory usage increase? Is there anywhere that it would decrease, ...
Hi, I was trying to understand the floating point representation in C using this code (both float and int are 4 bytes on my machine): int x = 3; float y = *(float*) &x; printf("%d %e \n", x, y); We know that the binary representation of x will be the following 00000000000000000000000000000011 Therefore I would have expected y to be...
