SYNOPSIS

#include <openssl/dh.h>
DH∗ DH_new(

DESCRIPTION

The DH_new() function allocates and initializes a DH structure. 

The DH_free() function frees the DH structure and its components. The values are erased before the memory is returned to the system. 

RETURN VALUES

If the allocation fails, the DH_new() function returns NULL and sets an error code that can be obtained from ERR_get_error(). Otherwise it returns a pointer to the newly allocated structure. 

The DH_free() function returns no value.

The DH_new() and DH_free() functions are available in all versions of SSLeay and OpenSSL.
