Differe between static and global parameters

Hi

Can some explain me very clearly what is the difference between static and global parameters in C language?

There is no such thing as a static parameter. There are static functions and static variables, but not static parameters (to functions).
A static function has visibility only within in the module. A static variable in a function retains its value after the function exits. A static variable a module scope retains its value through the life of the process and is initialized when the process starts.

Global (extern) is a variable that has visibility to all modules that are linked with that module. To use the global var in a module it has to be declared in an include file.

Global parameters can be accessed from other source files also using extern and they use global memory space, whereas Global static parameters cannot be used in other files and also are stored in the heap area and not on stacks or Global memory area. Whereas local static functions retain their values during funciton call and don't get destroyed even after function scope is over, they don't use stack rather they use heap memory.
