Detailed Description

template<typename C, typename T = filesystem_traits<C>>
class unixstl::basic_current_directory_scope< C, T >

Current directory scoping class.

This class scopes the process's current directory, by changing to the path given in the constructor, and then, if that succeeded, changing back in the destructor.

Parameters:

	C	The character type (e.g. char, wchar_t).
	T	The file-system traits. In translators that support default template parameters that defaults to filesystem_traits<C>.

State
	operator operator_bool_type () const
	Indicates whether the construction was successful.
Public Types
typedef C	char_type
Public Member Functions
	basic_current_directory_scope (char_type const *dir)
	Constructs a scope instance and changes to the given directory.
template<typename S>
	basic_current_directory_scope (S const &dir)
	Constructs a scope instance and changes to the given directory.
	~basic_current_directory_scope () throw ()
	Returns the current directory to its original location.
char_type const *	get_previous () const
	Returns a C-string pointer to the original directory.
	operator char_type const * () const
	Returns a C-string pointer to the original directory.
