5 DSA_SIG_new, DSA_SIG_free - allocate and free DSA signature objects

11 DSA_SIG *DSA_SIG_new(void);
12 void DSA_SIG_free(DSA_SIG *a);
13 void DSA_SIG_get0(BIGNUM **pr, BIGNUM **ps, const DSA_SIG *sig);
17 DSA_SIG_new() allocates and initializes a B<DSA_SIG> structure.
19 DSA_SIG_free() frees the B<DSA_SIG> structure and its components. The
20 values are erased before the memory is returned to the system.
22 DSA_SIG_get0() returns internal pointers the B<r> and B<s> values contained
23 in B<sig>. The values can then be examined or initialised.
27 If the allocation fails, DSA_SIG_new() returns B<NULL> and sets an
28 error code that can be obtained by
29 L<ERR_get_error(3)>. Otherwise it returns a pointer
30 to the newly allocated structure.
32 DSA_SIG_free() returns no value.
