bool is_block_file() const; bool is_block_file( std::error_code& ec ) const noexcept; | (since C++17) |
Checks whether the pointed-to object is a block device. Effectively returns std::filesystem::is_block_file(status()) or std::filesystem::is_block_file(status(ec)), respectively.
| ec | - | out-parameter for error reporting in the non-throwing overload |
true if the referred-to filesystem object is a block device, false otherwise.
The overload that does not take a std::error_code& parameter throws filesystem_error on underlying OS API errors, constructed with p as the first path argument and the OS error code as the error code argument. The overload taking a std::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. Any overload not marked noexcept may throw std::bad_alloc if memory allocation fails.
