157 \&\fIERR_print_errors()\fR is a convenience function that prints the error
158 strings for all errors that OpenSSL has recorded to \fBbp\fR, thus
159 emptying the error queue.
160 .PP
161 \&\fIERR_print_errors_fp()\fR is the same, except that the output goes to a
162 \&\fB\s-1FILE\s0\fR.
163 .PP
164 The error strings will have the following format:
165 .PP
166 .Vb 1
167 \& [pid]:error:[error code]:[library name]:[function name]:[reason string]:[file name]:[line]:[optional text message]
168 .Ve

170 \&\fIerror code\fR is an 8 digit hexadecimal number. \fIlibrary name\fR,
171 \&\fIfunction name\fR and \fIreason string\fR are \s-1ASCII\s0 text, as is \fIoptional
172 text message\fR if one was set for the respective error code.
173 .PP
174 If there is no text string registered for the given error code,
175 the error string will contain the numeric code.
