Member Function Documentation

◆ error_code()

virtual int Botan::Exception::error_code ( ) const
inlinevirtualnoexceptinherited

Return an error code associated with this exception, or otherwise 0.

The domain of this error varies depending on the source, for example on POSIX systems it might be errno, while on a Windows system it might be the result of GetLastError or WSAGetLastError.

Reimplemented in Botan::CommonCrypto_Error, Botan::Compression_Error, Botan::PKCS11::PKCS11_ReturnError, Botan::SQL_Database::SQL_DB_Error, Botan::System_Error, Botan::TLS::TLS_Exception, and Botan_FFI::FFI_Error.

Definition at line 107 of file exceptn.h.

107{ return 0; }

◆ error_type()

ErrorType Botan::Invalid_Authentication_Tag::error_type ( ) const
inlineoverridevirtualnoexcept

Return the "type" of error which occurred.

Reimplemented from Botan::Exception.

Definition at line 277 of file exceptn.h.

◆ 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.
