When a call to the native OpenSSL library fails, this is usually signalled by the return value, and an error code is stored in an error queue associated with the current thread. The err library provides functions to obtain these error codes and textual error messages. rN)libZ ERR_get_errorappendr ZERR_lib_error_stringZERR_func_error_stringZERR_reason_error_string)Zexception_typeerrorserrorr r r exception_from_error_queue"s    rcsfdd}|S)z~ Create an assert function that uses :func:`exception_from_error_queue` to raise an exception wrapped by *error*. cs|durtdS)zT If *ok* is not True, retrieve the error from OpenSSL and raise it.
