[edit]

Defined in header`<experimental/filesystem>`
bool status_known( file_status s);	(1)	(filesystem TS)

Checks if the given file status is known, Equivalent tos.type()!= file_type::none.

[edit]Parameters

file status to check

[edit]Return value

true if the given file status is an unknown file status.

[edit]Exceptions

noexcept specification:

noexcept

[edit]Notes

Despite the name, the function checks for the file status offile_type::none (meaning an error occurred), notfile_type::unknown (meaning file exists, but its type cannot be determined).
