I<buf> must be at least 120 -bytes long. If I<buf> is B<NULL>, the error string is placed in a -static buffer. -ERR_error_string_n() is a variant of ERR_error_string() that writes -at most I<len> characters (including the terminating 0) -and truncates the string if necessary. -For ERR_error_string_n(), I<buf> may not be B<NULL>. - -The string will have the following format: - - error:[error code]:[library name]:[function name]:[reason string] - -I<error code> is an 8 digit hexadecimal number, I<library name>, -I<function name> and I<reason string> are ASCII text. - -ERR_lib_error_string(), ERR_func_error_string() and -ERR_reason_error_string() return the library name, function -name and reason string respectively. - -The OpenSSL error strings should be loaded by calling -L<ERR_load_crypto_strings(3)|ERR_load_crypto_strings(3)> or, for SSL -applications, L<SSL_load_error_strings(3)|SSL_load_error_strings(3)> -first. -If there is no text string registered for the given error code, -the error string will contain the numeric code. - -L<ERR_print_errors(3)|ERR_print_errors(3)> can be used to print -all error codes currently in the queue. - -=head1 RETURN VALUES - -ERR_error_string() returns a pointer to a static buffer containing the -string if I<buf> B<== NULL>, I<buf> otherwise. - -ERR_lib_error_string(), ERR_func_error_string() and -ERR_reason_error_string() return the strings, and B<NULL> if -none is registered for the error code. - -=head1 SEE ALSO - -L<err(3)|err(3)>, L<ERR_get_error(3)|ERR_get_error(3)>, -L<ERR_load_crypto_strings(3)|ERR_load_crypto_strings(3)>, -L<SSL_load_error_strings(3)|SSL_load_error_strings(3)> -L<ERR_print_errors(3)|ERR_print_errors(3)> - -=head1 HISTORY - -ERR_error_string() is available in all versions of SSLeay and OpenSSL. -ERR_error_string_n() was added in OpenSSL 0.9.6. - -=cut |
