DH_new.3ssl - Man Page

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. 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.
