Merge #1368
1368: Fix fcntl for FreeBSD platform r=asomers a=AlexanderThaller
When compiling the following code with nix `0.19.1` under FreeBSD 12.2:
```
use std::os::unix::io::AsRawFd;
fn main() {
let f = std::fs::File::create("/tmp/testfile").unwrap();
nix::fcntl::posix_fadvise(
f.as_raw_fd(),
0,
0,
nix::fcntl::PosixFadviseAdvice::POSIX_FADV_NOREUSE,
).unwrap();
}
```
I get the following error:
```
error[E0433]: failed to resolve: could not find `PosixFadviseAdvice` in `fcntl`
--> src/main.rs:10:21
|
10 | nix::fcntl::PosixFadviseAdvice::POSIX_FADV_NOREUSE,
| ^^^^^^^^^^^^^^^^^^ could not find `PosixFadviseAdvice` in `fcntl`
error[E0425]: cannot find function `posix_fadvise` in module `nix::fcntl`
--> src/main.rs:6:17
|
6 | nix::fcntl::posix_fadvise(
| ^^^^^^^^^^^^^ not found in `nix::fcntl`
error: aborting due to 2 previous errors
```
Checking the documentation I noticed the documentation for the FreeBSD platform was missing:
https://docs.rs/nix/0.19.1/x86_64-unknown-freebsd/nix/?search=PosixFadviseAdvice
Checking the code I noticed that `target_env` was used instead of `target_os`:
* https://doc.rust-lang.org/reference/conditional-compilation.html#target_env
* https://doc.rust-lang.org/reference/conditional-compilation.html#target_os
Switching to `target_os` fixed the compilation errors. I also ran the tests with the fix and they seemed to be fine:
```
test result: ok. 68 passed; 0 failed; 14 ignored; 0 measured; 0 filtered out
```
I hope this makes sense to fix.
