In C programming, error handling is typically done using functions that handle runtime errors, returning error codes or messages to notify the programmer about the failure or incorrect operation.

Error handling in C code - Stack Overflow

I'd recommend to look at how Google handles errors in C++: abseil.io/docs/cpp/guides/status and implement something similar in C using Macros. Basically you have a struct: struct DataAndError { int returned_data; int error; } and then you get the value back making a regular call, and also check that the returned struct contains no error.

C Error Handling - Online Tutorials Library

Most of the C or even Unix function calls return -1 or NULL in case of any error and set an error code errno. It is set as a global variable and indicates an error occurred during any function call. You can find various error codes defined in <error.h> header file.

C Programming/Error handling - Wikibooks

By convention, the programmer is expected to prevent errors from occurring in the first place, and test return values from functions. For example, -1 and NULL are used in several functions such as socket () (Unix socket programming) or malloc () respectively to indicate problems that the programmer should be aware about.

8.5) Handling errors and exceptions in C - Free Cpp

Handling errors and exceptions in C programs involves anticipating and managing unexpected situations that can arise during program execution. C doesn’t have built-in exception handling like some other languages, but you can use various techniques to handle errors effectively. Let’s explore these techniques with explanations and examples:

C Language Error Handling - Studytonight

Whenever a function call is made in C language, a variable named errno is associated with it. It is a global variable, which can be used to identify which type of error was encountered while function execution, based on its value. Below we have the list of Error numbers and what does they mean.

Error Handling in C - FreeCodeCompiler

Error handling is an essential aspect of programming in C. Unlike some high-level languages with exception handling constructs, C relies on return values and a global variable called errno to communicate errors. Understanding how to properly handle errors allows you to build robust and reliable programs.
