Member Function Documentation

error_code()

int Botan::TLS::TLS_Exception::error_code ( ) const

inlineoverridevirtualnoexcept

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 from Botan::Exception.

Definition at line 26 of file tls_exceptn.h.

{ return static_cast<int>(m_alert_type); }

error_type()

ErrorType Botan::TLS::TLS_Exception::error_type ( ) const

inlineoverridevirtualnoexcept

Return the "type" of error which occurred.

Reimplemented from Botan::Exception.

Definition at line 28 of file tls_exceptn.h.

{ return ErrorType::TLSError; }

type()

Alert::Type Botan::TLS::TLS_Exception::type ( ) const

Definition at line 21 of file tls_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.

Definition at line 93 of file exceptn.h.

{ return m_msg.c_str(); }
