GOAL
Allow a golang library to be dependent on windows dlls and hide this from library consumers.
The reason I want to do this a lot of people prefer single file distributables. This code allows that. They embed the dll in the binary, and this will have some helper functions to load it. It accomplishes this by writing the binary to a temporary file. It remains for consideration in the future to use https://github.com/fancycode/MemoryModule.
Currently the code follows the pattern from https://www.drdobbs.com/packing-dlls-in-your-exe/184416443 (write file, open file with delete on close, load library). Cannot due this due to loadlibrary not allowing FILE_SHARE_DELETE
Currently this code copies the dll into windows temp directory. It does so with the following pattern.
tempdirectory/(base32 ecoded sha256)-(originalfilename)
The copied dll stays there forever.

Types ¶
type LazyDLL ¶
type LazyDLL struct {
Name string
// contains filtered or unexported fields
}
A LazyDLL implements access to a single DLL. It will delay the load of the DLL until the first call to its Handle method or to one of its LazyProc's Addr method.
func NewLazyDLL ¶
NewLazyDLL creates new LazyDLL associated with DLL file.
type LazyProc ¶
type LazyProc struct {
Name string
// contains filtered or unexported fields
}
A LazyProc implements access to a procedure inside a LazyDLL. It delays the lookup until the Addr, Call, or Find method is called.
func (*LazyProc) Addr ¶
Addr returns the address of the procedure represented by p. The return value can be passed to Syscall to run the procedure.
