Struct NativeLibrary 

pub struct NativeLibrary { /* private fields */ }

A library that was opened. It is never closed, so what it exports stays valid for the life of the process.

Implementations

impl NativeLibrary

pub fn open(name: &'static CStr) -> Result<Self, NativeLibraryError>

Opens the library of that name, as the dynamic loader finds it: its functions are bound when first called, and its symbols are available to the libraries loaded after it (RTLD_LAZY | RTLD_GLOBAL).

pub fn open_with_flags( name: &'static CStr, flags: c_int, ) -> Result<Self, NativeLibraryError>

Opens the library of that name with the flags of dlopen given (RTLD_NOW | RTLD_LOCAL, for one).

pub fn name(&self) -> &'static CStr

The name the library was opened by.

pub fn symbol(&self, symbol: &str) -> Result<*const c_void, NativeLibraryError>

The address of the function of that name.
