Additional Inherited Members
Public Types inherited from jau::os::DynamicLinker
typedef void *	libhandle_t
	library handle

typedef void *	symhandle_t
	symbol handle within a library

Public Member Functions inherited from jau::os::DynamicLinker
virtual	~DynamicLinker () noexcept=default

void	closeLibrary (libhandle_t handle) noexcept
	Security checks are implicit by previous call of `openLibraryLocal(const std::string_view&, boolean)` or `openLibraryGlobal(const std::string_view&, boolean)` retrieving the `librarHandle`.

std::string	getLastError () noexcept
	Returns a string containing the last error.

const char *	lookupLibraryPathname (libhandle_t handle, const std::string &symbolName) noexcept

symhandle_t	lookupSymbol (libhandle_t handle, const std::string &symbolName) noexcept

symhandle_t	lookupSymbolGlobal (const std::string &symbolName) noexcept

libhandle_t	openLibraryGlobal (const std::string &pathname) noexcept
	Opens the named library, allowing system wide access for other users.

libhandle_t	openLibraryLocal (const std::string &pathname) noexcept
	Opens the named library, restricting access to this process.

Static Public Member Functions inherited from jau::os::DynamicLinker
static std::vector< std::string >	enumerateLibraryPaths (const std::string &libName, bool searchSystemPath=false, bool searchSystemPathFirst=false) noexcept
	Returns list of potential absolute library filenames.

static DynamicLinker &	get () noexcept
	Returns static singleton instance of DynamicLinker.

static std::string	getBaseName (const std::string &filename, const bool isBasename=false, const bool caseInsensitive=jau::os::is_windows()) noexcept
	Returns the library basename, i.e.

static constexpr_cxx20 std::string	getCanonicalName (const std::string &basename, const bool checkIsCanonical=true) noexcept
	Returns canonical library name for this system from given library-basename, e.g.

static constexpr_cxx20 std::string	getDefaultPrefix () noexcept
	Returns the native library prefix, e.g.

static constexpr_cxx20 std::string	getDefaultSuffix () noexcept
	Returns the native library suffix including the dot, e.g.

static constexpr_cxx20 std::string	getEnvLibPathVarName () noexcept
	Returns the environment library path variable name, e.g.

static std::vector< std::string >	getSystemEnvLibraryPaths ()
	Returns a list of system paths, from the `getSystemEnvLibraryPathVarname()` variable.

static bool	isCanonicalName (const std::string &filename, const bool isBasename=false, const bool caseInsensitive=jau::os::is_windows()) noexcept
	Returns true if the given filename contains the canonical prefix and suffix, otherwise returns false.
