My FFI binding returns a struct with fixed-size c_char arrays, and I would like to turn those into std::ffi::CString or std::String. It looks like the CString::new function coerces the pointer to a vector. use std::ffi::CString; use std::os::raw::c_char; #[repr(C)] pub st...

Convert C++ byte array to a C string, Strings in C are byte arrays which are zero-terminated. So all you need to do is copy the array into a new buffer with sufficient space for a trailing zero byte: #include <string.h> #include <stdio.h> typedef unsigned char BYTE; int main() ...
