std::filesystem::directory_entry::file_size (3) - Linux Manuals
std::filesystem::directory_entry::file_size: std::filesystem::directory_entry::file_size
Command to display std::filesystem::directory_entry::file_size manual in Linux: $ man 3 std::filesystem::directory_entry::file_size
NAME
std::filesystem::directory_entry::file_size - std::filesystem::directory_entry::file_size
Synopsis
std::uintmax_t file_size() const; (since C++17)
std::uintmax_t file_size( std::error_code& ec ) const noexcept;
If the file size is cached in this directory_entry, returns the cached value. Otherwise, returns std::filesystem::file_size(path()) or std::filesystem::file_size(path(), ec), respectively
Parameters
ec - out-parameter for error reporting in the non-throwing overload
Return value
The size of the referred-to filesystem object
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.
