DH_new, DH_free ā€” allocate and free DH objects


 #include <openssl/dh.h>

 DH* DH_new(void);

 void DH_free(DH *dh);


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.
