.SH DESCRIPTION
.IX Header "DESCRIPTION"
\&\fBOSSL_PARAM_print_to_bio()\fR formats each parameter contained in the
passed in array of \fBOSSL_PARAM\fR values \fIp\fR, and prints both the key,
and optionally its value, to a provided \fBBIO\fR.
\&\fIp\fR must be a non-null array of OSSL_PARAM values, terminated
with a value containing a null \fIkey\fR member.
\&\fIprint_values\fR is a control parameter, indicating that key values should be
printed, in addition to key names.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
\&\fBOSSL_PARAM_print_to_bio()\fR returns 1 on success, and 0 on failure
.SH HISTORY
.IX Header "HISTORY"
\&\fBOSSL_PARAM_print_to_bio()\fR was added in OpenSSL 3.5
