How to access Global variables and functions

[dinesh123]

How can I access global variables and function in my VC++ applications

Thankx in advance

As long as the variable and function are not being declared as static in file scope, you need to declare them as extern in your calling file.

// Original file
int temp;
void foo(void);


// Calling file 
extern int temp;
extern void foo(void);

void bar(void)
{
    foo();
}

Of course, shared header files are much better
