List of all members.


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

Member Function Documentation

char_type const* get_previous (  )  const

Returns a C-string pointer to the original directory.

Referenced by unixstl::c_str_data(), unixstl::c_str_len(), unixstl::c_str_ptr(), and unixstl::c_str_ptr_null().

operator char_type const * (  )  const

Returns a C-string pointer to the original directory.

operator operator_bool_type (  )  const [inline]

Indicates whether the construction was successful.

Return values:
true The scope instance was successfully constructed and the current directory changed as per the constructor argument
false The scope instance was not successfully constructed, and the current directory was unchanged.
