std::filesystem::directory_entry::is_fifo
bool is_fifo() const; bool is_fifo( std::error_code& ec ) const noexcept; | (since C++17) |
Checks whether the pointed-to object is a FIFO or pipe file. Effectively returns std::filesystem::is_fifo(status())
or std::filesystem::is_fifo(status(ec))
, respectively.
Parameters
ec | - | out-parameter for error reporting in the non-throwing overload |
Return value
true if the referred-to filesystem object is a FIFO or pipe file, false otherwise.
Exceptions
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.
