Struct libloading::os::unix::Library
[−]
[src]
pub struct Library { /* fields omitted */ }A platform-specific equivalent of the cross-platform Library.
Methods
impl Library[src]
pub fn new<P: AsRef<OsStr>>(filename: P) -> Result<Library>[src]
Find and load a shared library (module).
Locations where library is searched for is platform specific and can’t be adjusted portably.
Corresponds to dlopen(filename, RTLD_NOW).
pub fn this() -> Library[src]
Load the dynamic libraries linked into main program.
This allows retrieving symbols from any dynamic library linked into the program, without specifying the exact library.
Corresponds to dlopen(NULL, RTLD_NOW).
pub fn open<P>(filename: Option<P>, flags: c_int) -> Result<Library> where
P: AsRef<OsStr>, [src]
P: AsRef<OsStr>,
Find and load a shared library (module).
Locations where library is searched for is platform specific and can’t be adjusted portably.
If the filename is None, null pointer is passed to dlopen.
Corresponds to dlopen(filename, flags).
pub unsafe fn get<T>(&self, symbol: &[u8]) -> Result<Symbol<T>>[src]
Get a pointer to function or static variable by symbol name.
The symbol may not contain any null bytes, with an exception of last byte. A null
terminated symbol may avoid a string allocation in some cases.
Symbol is interpreted as-is; no mangling is done. This means that symbols like x::y are
most likely invalid.
Unsafety
Pointer to a value of arbitrary type is returned. Using a value with wrong type is undefined.
Platform-specific behaviour
OS X uses some sort of lazy initialization scheme, which makes loading TLS variables impossible. Using a TLS variable loaded this way on OS X is undefined behaviour.
