NAME¶

std::experimental::filesystem::current_path - std::experimental::filesystem::current_path

Synopsis¶

Defined in header <experimental/filesystem>
path current_path(); (1) (filesystem TS)
path current_path( error_code& ec ); (2) (filesystem TS)
void current_path( const path& p ); (3) (filesystem TS)
void current_path( const path& p, error_code& ec ); (4) (filesystem TS)

Returns or changes the current path.

1-2) Returns the absolute path of the current working directory, obtained as if by
POSIX getcwd. (2) returns path() if error occurs.
3-4) Changes the current working directory to p, as if by POSIX chdir.

Parameters¶

p - path to change the current working directory to
ec - out-parameter for error reporting in the non-throwing overloads

Return value¶

1-2) Returns the current working directory.
3-4) (none)

Exceptions¶

1-2) The overload that does not take a error_code& parameter throws filesystem_error
on underlying OS API errors, constructed with the OS error code as the error code
argument. std::bad_alloc may be thrown if memory allocation fails. The overload
taking a error_code& parameter sets it to the OS API error code if an OS API call
fails, and executes ec.clear() if no errors occur. This overload has
noexcept specification:
noexcept
3-4) The overload that does not take a error_code& parameter throws filesystem_error
on underlying OS API errors, constructed with p as the first argument and the OS
error code as the error code argument. std::bad_alloc may be thrown if memory
allocation fails. The overload taking a error_code& parameter sets it to the OS API
error code if an OS API call fails, and executes ec.clear() if no errors occur. This
overload has
noexcept specification:
noexcept

Notes¶

The current working directory is the directory that is used as the starting location
in path resolution for relative paths. Single current working directory is
associated with entire process.

The current working directory is a dangerous global state of the program. Behavior
of various file input/output related functions are affected by the value of the
current path. The current path may be unexpectedly changed by any component of the
program, including various external libraries or other threads.
