| 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 | |
| 17 | DSA_new() allocates and initializes a B<DSA> structure. It is equivalent to |
| 18 | calling DSA_new_method(NULL). |
| 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. |
| 22 | If B<dsa> is NULL nothing is done. |
| 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 |
| 28 | L<ERR_get_error(3)>. Otherwise it returns a pointer |
| 29 | to the newly allocated structure. |
| 30 | |
| 31 | DSA_free() returns no value. |
