3 | =head1 NAME | |
4 | ||
5 | DSA_new, DSA_free - allocate and free DSA objects | |
6 | ||
7 | =head1 SYNOPSIS | |
8 | ||
9 | #include <openssl/dsa.h> | |
10 | ||
11 | DSA* DSA_new(void); | |
12 | ||
13 | void DSA_free(DSA *dsa); | |
14 | ||
15 | =head1 DESCRIPTION | |
16 | ||
5bf73873 GT |
17 | DSA_new() allocates and initializes a B<DSA> structure. It is equivalent to |
18 | calling DSA_new_method(NULL). | |
38e33cef UM |
19 | |
20 | DSA_free() frees the B<DSA> structure and its components. The values are | |
21 | erased before the memory is returned to the system. | |
d6407083 | 22 | If B<dsa> is NULL nothing is done. |
38e33cef UM |
23 | |
24 | =head1 RETURN VALUES | |
25 | ||
26 | If the allocation fails, DSA_new() returns B<NULL> and sets an error | |
27 | code that can be obtained by | |
9b86974e | 28 | L<ERR_get_error(3)>. Otherwise it returns a pointer |
38e33cef UM |
29 | to the newly allocated structure. |
30 | ||
31 | DSA_free() returns no value. | |
