It is a preprocessor directive that basically performs the same thing as
/* until the next #endif, which becomes the same thing as */.

In other words, the code between #if 0 and #endif is zapped by the
preprocessor before it reaches the compiler.

This should be a well-known fact; any decent C/C++ programmer should
understand each and all the preprocessor directives.
