2019-5-7 · The extern “C” keyword is used to make a function name in C++ have the C linkage. In this case the compiler does not mangle the function. Let us see what is the mangling in C++ first, then we can discuss about the extern “C” keyword. In C++ we can use the function overloading feature. Using this feature, we can create functions with

#include /* Allow for C++ users */ #ifdef __cplusplus extern "C" void (*pcre_free)(void *); /* Functions */ extern pcre *pcre_compile(const char *, int, 

Variable declaration. extern int a; · // file1.h. // Contains function prototypes for  reent/writer.c assumes the OS layer stores errno in extern int errno.

The extern storage class specifier can modify a declaration in one of the three following ways, depending on context: It can be used to declare a variable without defining it. Typically, this is used in a header file for a variable that will be defined in a separate implementation file. // global scope int x; // definition; x will be The extern keyword has four meanings depending on the context: In a non- const global variable declaration, extern specifies that the variable or function is defined in another translation unit. The extern must be applied in all files except the one where the variable is defined.

The prototypes are available in dll.h in the “include” directory. Return codes are given at the end.

By default the functions are visible throughout the program, there is no need to declare or define extern functions. It just increase the redundancy.
