write is a system call, and you have write as a local function name. At best this becomes a never-ending recursive call.

Call your function mywrite() or something else, do not name your functions the same thing as syscalls, -read write open and so on.

Interposition is acheived by writing a shared library module (call it mylibrary.so as an example), compling it, then creating a special environment variable, LD_PRELOAD=mylibrary.so, and then running your code. But you still cannot do what your code shows.
