Can a static function defined in a C file be ever referred (called)
externally from another C file?If so in which conditions?

only when you include the file(in which static function is defined) in
another C file(in which you want to use)
jeniffer opined: Can a static function defined in a C file be ever referred (called)

Yes, if you declare a variable to be a pointer to such a function, and
make it point to that function (obviously this has to be done in the
file where `static` function is). If that pointer is not static, it
can be used from elsewhere to call that function.
It may help if you think of function /names/, they're not accessible.

Also, your answer is wrong. Including a file into another makes it a
part of that file, and thus irrelevant to the original question. See
my other post for the correct answer.

Yes. Through a pointer-to-function that has been assigned the address
of the static function. The pointer must have external linkage and the
assignment done in the compilation unit containing the static function.
This allows a compilation unit to have several candidate static
functions and a function which can choose which one is to be used. ji************@ gmail.com wrote: only when you include the file(in which static function is defined) in

This is incorrect. A pointer-to-function with external linkage will do
the job.

Is this a homework question?
If you want to call a function from another C file, don't make it
static.
(That doesn't answer your original question.)

No, it's still a separate file but it becomes part of the same
translation unit. The information is correct, but it's not the "only"
way. jj*@bcs.org.uk wrote: Vladimir S. Oka wrote: ji************@ gmail.com opined: jeniffer wrote:

If you want to call a function from another C file, don't make it
static.
This situation is not just academic. Consider a callback function
implementation. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |

I am writing a script where I need to use the system() function to call

I have a question about mixing C and C++.
In a C++ translation unit, I want to define a function with internal
