dlclose(DynamicLibrary handle) → int: Available on Stdc, provided by the StdcDlfcn extension
Decrements the reference count on the dynamic library handle. Note: dart:ffi does not currently provide a way to explicitly close a DynamicLibrary. This function acts as a no-op but returns 0 for success.
dlerror() → String?: Available on Stdc, provided by the StdcDlfcn extension
Returns a human-readable string describing the most recent error that occurred from dlopen(), dlsym() or dlclose() since the last call to dlerror().
dlopen(String? filename, int flag) → DynamicLibrary?: Available on Stdc, provided by the StdcDlfcn extension
Loads the dynamic library file named by the null-terminated string filename and returns an opaque "handle" for the dynamic library.
dlsym<T extends NativeType>(DynamicLibrary handle, String symbol) → Pointer<T>?: Available on Stdc, provided by the StdcDlfcn extension
Takes a "handle" of a dynamic library returned by dlopen() and the null-terminated symbol name, returning the address where that symbol is loaded into memory.
