77 is a convenience function that prints the error strings for all errors
78 that OpenSSL has recorded to
80 thus emptying the error queue.

83 is the same, except that the output goes to a
86 .Fn ERR_print_errors_cb
87 is the same, except that the callback function,
89 is called for each error line with the string, length, and userdata
91 as the callback parameters.
93 The error strings have the following format:
95 [pid]:error:[error code]:[library name]:[function name]:[reason string]:
96 [file name]:[line]:[optional text message]
99 The error code is an 8-digit hexadecimal number.
100 The library name, the function name, and the reason string are ASCII
101 text, as is the optional text message if one was set for the
102 respective error code.
104 If there is no text string registered for the given error code, the
105 error string will contain the numeric code.
