DH_new(3)                    OpenSSL                    DH_new(3)

NAME

     DH_new, DH_free - allocate and free DH objects

SYNOPSIS

      #include <openssl/dh.h>

      DH* DH_new(void);

      void DH_free(DH *dh);

DESCRIPTION

     DH_new() allocates and initializes a DH structure.

     DH_free() 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, DH_new() returns NULL and sets an
     error code that can be obtained by ERR_get_error(3).
     Otherwise it returns a pointer to the newly allocated
     structure.

     DH_free() returns no value.

HISTORY
