bool filesystem::is_regular_file(file_status s) noexcept;

1

#

Returns: s.type() == file_type​::​regular.

🔗

bool filesystem::is_regular_file(const path& p);

2

#

Returns: is_regular_file(status(p)).

3

#

Throws: filesystem_error if status(p) would throw filesystem_error.

🔗

bool filesystem::is_regular_file(const path& p, error_code& ec) noexcept;

4

#

Effects: Sets ec as if by status(p, ec).

[Note 1:

file_type​::​none, file_type​::​not_found and file_type​::​unknown cases set ec to error values.

To distinguish between cases, call the status function directly.

— end note]

5

#

Returns: is_regular_file(status(p, ec)).

Returns false if an error occurs.
