Crate auxv [−] [src]

Calls through to the underlying glibc getauxval(). Unfortunately, prior to glibc 2.19, getauxval() returns 0 without setting errno if the type is not found, so on such old systems this will return Ok(0) rather than Err(GetauxvalError::NotFound).

A stub implementation that always returns NotFound. This can be used when you want to use something reasonable (i.e. won't crash) that's not NativeGetauxvalProvider on non-Linux systems.

Read from the procfs auxv file and look for the specified types.
