Crate glibc_version 

Crate to help rust projects discover GNU libc version at build time. Expected to be used in build.rs. Note that this crate is only expected to work under cfg(target_env = "gnu"), so please guard the usage under relevant configuration predicates.

Example

let ver = glibc_version::get_version().unwrap();
if ver.major >= 2 && ver.minor >= 28 {
   println!("cargo:rustc-cfg=glibc_renameat2");
}
