.\&quot; Set up some character translations and predefined strings.  \*(-- will
.\&quot; give an unbreakable dash, \*(PI will give pi, \*(L&quot; will give a left
.\&quot; double quote, and \*(R&quot; will give a right double quote.  \*(C+ will
.\&quot; give a nicer C++.  Capital omega is used to do unbreakable dashes and
.\&quot; therefore won't be available.  \*(C` and \*(C' expand to `' in nroff,
.\&quot; nothing in troff, for use with C&lt;&gt;.

.\&quot; If the F register is &gt;0, we'll generate index entries on stderr for
.\&quot; titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
.\&quot; entries marked with X&lt;&gt; in POD.  Of course, you'll have to process the
.\&quot; output yourself in some meaningful fashion.
.\&quot;
.\&quot; Avoid warning from groff about undefined register 'F'.

.IX Header &quot;DESCRIPTION&quot;
\&amp;\fBEVP_PKEY_meth_count()\fR returns a count of the number of public key methods
available: it includes standard methods and any methods added by the
application.
.PP
\&amp;\fBEVP_PKEY_meth_get0()\fR returns the public key method \fBidx\fR. The value of \fBidx\fR
must be between zero and \fBEVP_PKEY_meth_get_count()\fR \- 1.
.PP
\&amp;\fBEVP_PKEY_meth_get0_info()\fR returns the public key \s-1ID\s0 (a \s-1NID\s0) and any flags
associated with the public key method \fB*meth\fR.
.SH &quot;RETURN VALUES&quot;
.IX Header &quot;RETURN VALUES&quot;
\&amp;\fBEVP_PKEY_meth_count()\fR returns the number of available public key methods.
.PP
\&amp;\fBEVP_PKEY_meth_get0()\fR return a public key method or \fB\s-1NULL\s0\fR if \fBidx\fR is
out of range.
.PP
\&amp;\fBEVP_PKEY_meth_get0_info()\fR does not return a value.
