Wirekits implement an "init" function that takes as parameter a pointer to a collection of syscall hooks (and additional context data). The first 1024 or so are in an array, the others in a binary search tree. During initialization, provided functions can be used to add hooks.

Next, a "run" function is called with the provided command line arguments. A provided function can be used to make "rewire" run a command in the adjusted environment. A call to this function should typically be the last step in "run".

Each hook takes a process control block pointer as argument. Additional functions are provided to e.g. interact with tracee memory.
