Detailed Description

Output stream implementation using the Unix low-level IO system (only on OSes supporting POSIX).

Constructor & Destructor Documentation

UnixOutStream()

UnixOutStream

(

int

_fd

)

Build an Unix output stream.

Parameters

fd	File descriptor.

Build a Unix output stream using a file descriptor identifier.

Parameters

_fd	File descriptor identifier.

References UnixOutStream::fd().

~UnixOutStream()

~UnixOutStream

(

)

Close an Unix output stream.

References UnixOutStream::_fd.

Member Function Documentation

fd()

int fd ( void  ) const

inline

References UnixOutStream::_fd.

Referenced by UnixOutStream::UnixOutStream().

flush()

int flush ( )

overridevirtual

Cause the current stream to dump its buffer to the medium.

Returns

0 for success, less than 0 for error.

Implements OutStream.

lastErrorMessage()

CString lastErrorMessage ( )

overridevirtual

Return the last occurred error message.

Returns

Last error message.

Reimplemented from OutStream.

supportsANSI()

bool supportsANSI ( ) const

overridevirtual

Test if the current stream knows how to decode ANSI special codes. The default implementation returns false.

Returns

True if ANSI code are supported, false else.

Reimplemented from OutStream.

References UnixOutStream::_fd.

write()

int write ( const char *  buffer, int  size  )

overridevirtual

This is the main method of an output stream: the given buffer is put on the stream.

Parameters

buffer	Byte buffer to write.
size	Size of the byte buffer.

Returns

Number of transferred bytes or less than 0 for an error.

Implements OutStream.

References UnixOutStream::_fd, and elm::io::write().
