Detailed Description

template<typename C>
struct winstl::moddir_policy< C >

Represents the directory of a module.

How

An instance of basic_module_directory encapsulates the directory of a given module. You instantiate it from a given module handle, as follows:

[STLSOFT-DOC:VERBATIM:start;comment:/// ;] HINSTANCE hinst = . . .; basic_module_directory<char>(hinst) mdir(hinst); puts(mdir); [STLSOFT-DOC:VERBATIM:end]

You can also use one of the three given typedefs: module_directory (parameterised on TCHAR), module_directory_a (parameterised on CHAR), module_directory_w (parameterised on WCHAR).

Why

1. It affords a simpler syntax. You can use temporary instances of the class, and use the char_type const* implicit conversion, or the c_str() method inline

[STLSOFT-DOC:VERBATIM:start;comment:/// ;] puts(module_directory_a(hinst)); [STLSOFT-DOC:VERBATIM:end]

You can also use it with the IOStreams:

[STLSOFT-DOC:VERBATIM:start;comment:/// ;] cout << L"The module was loaded from the " << module_directory_w(hinst) << L" directory" << endl; [STLSOFT-DOC:VERBATIM:end]

2. It relieves you from the boilerplate coding of calling GetModuleFileName() and then parsing the returned path to trim off the directory. All that is handled in the class.

Parameters:

	C	The character type
	T	The traits type. On translators that support default template arguments, this defaults to filesystem_traits<C>
