std::experimental::filesystem::is_fifo: std::experimental::filesystem::is_fifo

Command to display std::experimental::filesystem::is_fifo manual in Linux: $ man 3 std::experimental::filesystem::is_fifo

NAME

std::experimental::filesystem::is_fifo - std::experimental::filesystem::is_fifo

Synopsis

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

Checks if the given file status or path corresponds to a FIFO or pipe file.
1) Equivalent to s.type() == file_type::fifo.
2) Equivalent to is_fifo(status(p)).
3) Equivalent to is_fifo(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 query
ec - error code to modify in case of errors

Return value

true if the given path or file status corresponds to a FIFO file.

Exceptions

1,3)
noexcept specification:
noexcept
2) Throws filesystem_error if an error occurs. The exception object is constructed with p as an argument.
