16=head1 DESCRIPTION
17
18EVP_PKEY_meth_count() returns a count of the number of public key methods
19available: it includes standard methods and any methods added by the
20application.
21
22EVP_PKEY_meth_get0() returns the public key method B<idx>. The value of B<idx>
23must be between zero and EVP_PKEY_meth_get_count() - 1.
24
25EVP_PKEY_meth_get0_info() returns the public key ID (a NID) and any flags
26associated with the public key method B<*meth>.
27
28=head1 RETURN VALUES
29
30EVP_PKEY_meth_count() returns the number of available public key methods.
31
32EVP_PKEY_meth_get0() return a public key method or B<NULL> if B<idx> is
33out of range.
34
35EVP_PKEY_meth_get0_info() does not return a value.
