=head1 NAME
EVP_PKEY_meth_get_count, EVP_PKEY_meth_get0, EVP_PKEY_meth_get0_info - enumerate public key methods
=head1 SYNOPSIS
#include <openssl/evp.h>
size_t EVP_PKEY_meth_get_count(void);
const EVP_PKEY_METHOD *EVP_PKEY_meth_get0(size_t idx);
void EVP_PKEY_meth_get0_info(int *ppkey_id, int *pflags,
const EVP_PKEY_METHOD *meth);
=head1 DESCRIPTION
EVP_PKEY_meth_count() returns a count of the number of public key methods
available: it includes standard methods and any methods added by the
application.
EVP_PKEY_meth_get0() returns the public key method B<idx>. The value of B<idx>
must be between zero and EVP_PKEY_meth_get_count() - 1.
EVP_PKEY_meth_get0_info() returns the public key ID (a NID) and any flags
associated with the public key method B<*meth>.
=head1 RETURN VALUES
EVP_PKEY_meth_count() returns the number of available public key methods.
EVP_PKEY_meth_get0() return a public key method or B<NULL> if B<idx> is
out of range.
EVP_PKEY_meth_get0_info() does not return a value.
