I set a signal handler in ocaml to handle SIGINT. I also have some C
library functions that I wrapped using the FFI. If one of the C
functions is executing when the signal is thrown the signal is not
handled immediately. Instead, the C function continues to execute
normally, and the signal handler is invoked when the C function exits.
Is this what should be happening? What is the best way to have the
signal handled normally? Is the only way to do so to write a C signal
handler, wrap it, and invoke it from my Ocaml code before any of the C
library functions are called.
