Constructor & Destructor Documentation

Module() [1/3]

Botan::PKCS11::Module::Module	(	std::string_view	file_path,
		C_InitializeArgs	init_args = { nullptr, nullptr, nullptr, nullptr, static_cast<CK_FLAGS>(Flag::OsLockingOk), nullptr} )

Loads the shared library and calls C_Initialize

Parameters

file_path	the path to the PKCS#11 shared library
init_args	flags to use for C_Initialize

Definition at line 15 of file p11_module.cpp.
