d2i_DHparams, i2d_DHparams

 #include <openssl/dh.h>
 DH *d2i_DHparams(DH **a, unsigned char **pp, long length);
 int i2d_DHparams(DH *a, unsigned char **pp);

These functions decode and encode PKCS#3 DH parameters using the DHparameter structure described in PKCS#3.

Othewise these behave in a similar way to d2i_X509() and i2d_X509() described in the d2i_X509(3) manual page.
