I dont understand why one needs a static method in C. I have heard of static variables in a method. But not a static method itself. Could you please let me know what it is.

Say that you have a
File called _test_static and
function (static void foo) inside this file.
WITHOUT the word static at the beginning of the function declaration, the function becomes a global function. If any file #includes _test_static, It can not call the function. So basically the static keyword makes it visible only within _test_static file. Hope that helps.

thanks khoa

Static function has scope visibility for the file in which it is defined.

Yes.. at the expense of being pedantic, its called "internal linkage". So, non static functions will have external linkage. This concept is implemented both in C & in C++. Regardless of whether a function name has internal or external linkage, it has File scope (assuming its declared outside all blocks).
