3 | =head1 NAME | |
4 | ||
5 | DH_new, DH_free - allocate and free DH objects | |
6 | ||
7 | =head1 SYNOPSIS | |
8 | ||
9 | #include <openssl/dh.h> | |
10 | ||
11 | DH* DH_new(void); | |
12 | ||

15 | =head1 DESCRIPTION | |
16 | ||
17 | DH_new() allocates and initializes a B<DH> structure. | |
18 | ||
19 | DH_free() frees the B<DH> structure and its components. The values are | |
20 | erased before the memory is returned to the system. | |
d6407083 | 21 | If B<dh> is NULL nothing is done. |

22 | |
23 | =head1 RETURN VALUES | |
24 | ||
25 | If the allocation fails, DH_new() returns B<NULL> and sets an error | |
bb075f88 | 26 | code that can be obtained by L<ERR_get_error(3)|ERR_get_error(3)>. Otherwise it returns |
4486d0cd UM |
27 | a pointer to the newly allocated structure. |
28 | ||
29 | DH_free() returns no value. | |
