Detailed Description

The IoIntfCspReader, which implements the abstract CspReader interface, makes it possible to open a "CSP dat" file via a IoIntf.

Constructor & Destructor Documentation

IoIntfCspReader::IoIntfCspReader ( )

Uninitialized storage; initialize before use or destruction.

IoIntfCspReader::IoIntfCspReader	(	IoIntf *	io,
		const char *	pathName
	)

The IoIntfCspReader constructor opens the CSP data file for reading.

Parameters

io	Borrowed seekable I/O interface, valid until this reader closes.
pathName	Required NUL-terminated path within io to the data file generated by httpLink; used during construction only. Check inherited CspReader::isValid before use. A stat/open failure leaves the reader invalid. Debug builds call baFatalE if the initial magic number cannot be read or does not match the CSP data format.

IoIntfCspReader::~IoIntfCspReader ( )

Close an open file, ignoring the close status.

Stop all users of this reader before destruction.

int IoIntfCspReader::close ( )

Close and consume the file handle, even if closing fails.

Stop all reads first. The inherited isValid flag is not cleared; never use it to decide whether reading after close is safe.

Returns: Zero on success, the underlying negative close error, or -1 if the file is not open.
