File Information

Library: Foundation
Package: Streams
Header: Poco/FileStream.h

Description

An input stream for reading from a file.

Files are always opened in binary mode, a text mode with CR-LF translation is not supported. Thus, the file is always opened as if the std::ios::binary flag was specified. Use an InputLineEndingConverter if you require CR-LF translation.

On Windows platforms, UTF-8 encoded Unicode paths are correctly handled.
