Ok, so I am working with a PIC microprocessor, in C. It's a 16F, so it can't hold integers larger than 32bits (unsigned int32 is the largest datasize available) From a reader, I receive a 5 byte ID code. To transmit it, I have to encoded to BCD, digit by digit. I can't sprint it to a string, as it is larger that the data size, and can't...

I had an application installed on my windows machine which I removed, but it has left an orphaned drive icon under "My Computer". Having dug through the registry, to find it by name, it seems to be associated with a GUID that occurs in other parts of the registry. I'd like to write a quick C program to do the job, once I understand wha...
Hi, I'm working on a small academic research about extremely long and complicated functions in the Linux kernel. I'm trying to figure out if there is a good reason to write 600 or 800 lines-long functions. For that purpose, I would like to find a tool that can extract a function from a .c file, so I can run some automated tests on the ...

I'm reading through the manpage for dlopen and friends on FreeBSD. I'm working on a cross-platform application that is using shared libraries for loadable plugins. I've never done this before, but I think I have a decent grasp of how it works. The manpage mentions dlsym(), which appears to be the common means of getting a function pointe...
Hi, I am writing an academic project about extremely long functions in the Linux kernel. For that purpose, I am looking for examples for real-life functions that are extremely long (few hundreds of lines of code), that you don't consider bad programming (i.e., they won't benefit from decomposition or usage of a dispatch table). Have y...
I need to pass const char * to a function. Before I pass it, I usually need to build it from some variables. I can never decide which approach is more elegant, and overall better: Allocate an array long enough to fit the text and use sprintf to build the final variable and pass it to the function. Initialize string s with a variable us...
Hello everyone! I am writing a C program that produces a large output file. To increase readability, I would like to collect certain kinds of output at certain points in the file rather than have it be scattered randomly about. Consider a file like: log log (a) output output output(b) Say the program is currently writing the line a...

I'm working on a hot-upgrade feature and need to package up an array of structs to be stashed away for the new version to find them. I really want to avoid adding a conversion function for every possible version transition. Is this reasonable? The most likely change to the struct is for more fields to be added to the structure in the f...
