Constructor & Destructor Documentation

vul_redirector::vul_redirector ( vcl_ostream & s )

Attach redirector to vcl_ostream s, so that all future output to s goes through this->putchunk.

Definition at line 97 of file vul_redirector.cxx.

vul_redirector::~vul_redirector ( ) [virtual]

Destroy redirector, restore stream to original.

Definition at line 112 of file vul_redirector.cxx.

vcl_streamsize vul_redirector::put_passthru	(	char const *	buf,
		vcl_streamsize	n
	)		`[protected]`

Put characters to original stream.

Useful for derived classes which wish to filter a stream.

vcl_streamsize vul_redirector::putchunk	(	char const *	buf,
		vcl_streamsize	n
	)		`[virtual]`

The filter function.

Default action is just to pass text on the old stream.

Called with `n' characters in `buf', do with as you like.

Definition at line 146 of file vul_redirector.cxx.

int vul_redirector::sync_passthru ( ) [protected]
