# rs-libc This is a subset of libc that can be used with Rust inside SGX. Functions are added on an as-needed basis. ## errno `errno` is not supported. Functions that have had `errno` functionality removed: * `strtod` * `strtof` * `strtoimax` * `strtol` * `strtold` * `strtoll` * `strtoul` * `strtoull` * `strtoumax`
