Member Function Documentation

◆ error_code()

int Botan_FFI::FFI_Error::error_code ( ) const

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 24 of file ffi_util.h.

24{ return m_err_code; }

◆ error_type()

Botan::ErrorType Botan_FFI::FFI_Error::error_type ( ) const

Return the "type" of error which occurred.

Reimplemented from Botan::Exception.

Definition at line 26 of file ffi_util.h.

References Botan::InvalidArgument.

Referenced by Botan_FFI::ffi_guard_thunk().

◆ what()

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

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.
