I must be at least 120 +bytes long. If I is B, 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 characters (including the terminating 0) +and truncates the string if necessary. +For ERR_error_string_n(), I may not be B. + +The string will have the following format: + + error:[error code]:[library name]:[function name]:[reason string] + +I is an 8 digit hexadecimal number, I, +I and I 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 or, for SSL +applications, L +first. +If there is no text string registered for the given error code, +the error string will contain the numeric code. + +L 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 B<== NULL>, I otherwise. + +ERR_lib_error_string(), ERR_func_error_string() and +ERR_reason_error_string() return the strings, and B if +none is registered for the error code. + +=head1 SEE ALSO + +L, L, +L, +L +L + +=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
