| =head1 NAME | |
| DH_size - get Diffie-Hellman prime size | |
| =head1 SYNOPSIS | |
| #include <openssl/dh.h> | |
| int DH_size(DH *dh); | |
| =head1 DESCRIPTION | |
| This function returns the Diffie-Hellman size in bytes. It can be used | |
| to determine how much memory must be allocated for the shared secret | |
| computed by DH_compute_key(). | |
| B<dh-E<gt>p> must not be B<NULL>. | |
| =head1 RETURN VALUE | |
| The size in bytes. | |
| =head1 SEE ALSO | |
| L<dh(3)|dh(3)>, L<DH_generate_key(3)|DH_generate_key(3)> | |
