Defined in header <experimental/filesystem>
bool is_character_file( file_status s );	(1)	(filesystem TS)
bool is_character_file( const path& p );	(2)	(filesystem TS)
bool is_character_file( const path& p, error_code& ec );	(3)	(filesystem TS)

Checks if the given file status or path corresponds to a character special file.

1) Equivalent to s.type() == file_type::character.

2) Equivalent to is_character_file(status(p)).

3) Equivalent to is_character_file(status(p, ec)). Returns false and sets ec to an appropriate error code if an error occurs. Otherwise, ec is cleared with a call to ec.clear().

Parameters

s	-	file status to check
p	-	path to examine
ec	-	error code to store the error status to

Return value

true if the given path or file status corresponds to a character special file, false otherwise.

2) filesystem_error if an error occurs. The exception object is constructed with p as an argument. The error code is set to an appropriate error code for the error that caused the failure.
