Hi, I have the following line of

[unirams]

Hi,
I have the following line of codes in my library file(.h).

#ifdef __cplusplus
extern "C" {
#endif

extern void function(int a, int b);
extern void function2(int x, int y);

#ifdef __cplusplus
}
#endif

But i didn't find out the exact declaration and definition place of the abovementioned 2 functions function1, function2.

Any idea Please?

Thanks in advance.

Ram,

extern becomes redundant when it comes to function in the
global namespace.

i,e,
if you declare a function as

void func(void);
or
extern void func(void);

and if the defination exists in
some other file than both the declaration does the same thing.
