Use of static in functions

[Halid Umar A M]

Dear All,
Please help me to understand the use of static in a function.
What is the use of a function to be static in a module? For example in
a network applications there will be a common function to convert the
address to decimal dotted notation. It can be written as
static char *addr_to_dotted(unsigned long int addrp){ }

what is the use of static there? Please explain me.

Regards,
Halid Umar

Your teacher, or your textbook, should have explained this.

It means that that declaration will not be visible outside that
translation unit.
