# 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. If dh is NULL nothing is done.

# 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.
