Constructor & Destructor Documentation

Compression_Error()

Botan::Compression_Error::Compression_Error	(	const char *	func_name,
		ErrorType	type,
		int	rc )

Create a Compression_Error

Parameters

func_name	the name of the compression API that was called (eg "BZ2_bzCompressInit" or "lzma_code")
type	what library this came from
rc	the error return code from the compression API. The interpretation of this value will depend on the library.

Member Function Documentation

error_code()

int Botan::Compression_Error::error_code ( ) const

inlineoverridevirtualnoexcept

Return the library specific error code

Returns

the return code from the underlying compression API

Reimplemented from Botan::Exception.

Definition at line 199 of file compression.h.

{ return m_rc; }

error_type()

ErrorType Botan::Compression_Error::error_type ( ) const

inlineoverridevirtualnoexcept

Return the error type of this exception

Returns

the error type passed at construction

Reimplemented from Botan::Exception.

Definition at line 193 of file compression.h.

{ return m_type; }

what()

const char * Botan::Exception::what ( ) const

inlineoverridenoexceptinherited

Return a descriptive string which is hopefully comprehensible to a developer. It will likely not be useful for an end user.

The string has no particular format, and the content of exception messages may change from release to release. Thus the main use of this function is for logging or debugging.
