In this blog, you will learn about functions in C programming, including their definition, types, and how to use them to make your code more modular and efficient.
Thestaticspecifier signifies that the function can't be referenced from other files; that is, the name isn't exported by the linker. If no storage class appears in a function definition,externis assumed. In any case, the function is always visible from the definition point to the end of ...
Sigaction Type Structures in the C Language The “sigaction” type structure is meant to contain the data that configures an action. We can see such a structure in the following: struct sigaction{ void(*sa_handler)(int); void(*sa_sigaction)(int, siginfo_t*, void*); ...
The example below showcases the implementation of an inline function in C++. Code Example: #include<iostream> using namespace std; // Use the keyword "inline" to define an inline function inline int sum(int a, int b) { // Definition of inline function return a + b; } int main() {...
Syntax of the Strdup() Function in C language char*strdup(const char*str); Description of the Strdup() Function in C language The strdup() function duplicates a string. This function duplicates the string that is pointed to by the str pointer which is passed in the input argument, and ret...

Declaration: the function's name, return type, and parameters (if any) Definition: the body of the function (code to be executed)void myFunction() { // declaration // the body of the function (definition)}For code optimization, it is recommended to separate the declaration and the ...
Applied to a function declaration, the extern keyword in fact does nothing: the declaration extern int incr(int) is exactly the same as int incr(int). This is because all function declarations have an implicit extern applied! This also applies to function definitions: the function definition ...
