.SH NAME
ERR_print_errors, ERR_print_errors_fp \- print error messages
.SH SYNOPSIS
.IX Header "SYNOPSIS"
.Vb 1
\& #include <openssl/err.h>
\&
\& void ERR_print_errors(BIO *bp);
\& void ERR_print_errors_fp(FILE *fp);
.Ve
.SH DESCRIPTION
.IX Header "DESCRIPTION"
\&\fBERR_print_errors()\fR is a convenience function that prints the error
strings for all errors that OpenSSL has recorded to \fBbp\fR, thus
emptying the error queue.
.PP
\&\fBERR_print_errors_fp()\fR is the same, except that the output goes to a
\&\fBFILE\fR.
.PP
The error strings will have the following format:
.PP
.Vb 1
\& [pid]:error:[error code]:[library name]:[function name]:[reason string]:[file name]:[line]:[optional text message]
.Ve
.PP
\&\fIerror code\fR is an 8 digit hexadecimal number. \fIlibrary name\fR,
\&\fIfunction name\fR and \fIreason string\fR are ASCII text, as is \fIoptional
text message\fR if one was set for the respective error code.
.PP
If there is no text string registered for the given error code,
the error string will contain the numeric code.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
\&\fBERR_print_errors()\fR and \fBERR_print_errors_fp()\fR return no values.
.SH "SEE ALSO"

\&\fBERR_print_errors()\fR and \fBERR_print_errors_fp()\fR
are available in all versions of SSLeay and OpenSSL.
