DH_new (3openssl)

Name

DH_new - allocate and free DH objects

Synopsis

#include <openssl/dh.h>

DH* DH_new(void);

void DH_free(DH *dh);

Description

DH_new(3openssl)                    OpenSSL                   DH_new(3openssl)



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.
