d2i_DHparams, i2d_DHparams - PKCS#3 DH parameter functions.
#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 manual page.
