When you write a C program, you must create stub functions to represent functions that other parts of your program will call. This tutorial will show you how to do it in an easy way.
What are strains?
Stubs are snippets of code that represent a function or group of functions, but are not actually executed. They are used to test the functionality of a function by calling it with specific input values.
Definition of stubs for functions called by main() below.
Stubs are programs that let you test the functionality of a function without actually running it. This can be useful when you want to make sure a function call is behaving correctly, but you don’t have access to the source code.
To create a stub, you first need to know the name of the function and its corresponding source code. You can then create a simple program that prints the function name and definition.
Here is an example :
#include int main() { printf(“The function called by main() is %s.
“, __func__); returns 0; }
The function called by main() is printf().
Conclusion
Stubs are a method used in C programming to define functions that are not actually implemented. When a program calls a stub function, the program obtains an implementation of the function from a specially named library file. This allows you to write your programs without having to worry about how functions will be implemented (assuming you have access to the appropriate library) and it also makes debugging and testing easier.
Common questions
Q: What is a stub?
A: A stub is a block of code that represents the input and output of a function, without actually executing the function. This can be used to verify the correctness of code that calls a function or to test functions before using them in your program.
