5 DSA_SIG_new, DSA_SIG_free - allocate and free DSA signature objects
9 #include <openssl/dsa.h>
11 DSA_SIG *DSA_SIG_new(void);
12 void DSA_SIG_free(DSA_SIG *a);
13 void DSA_SIG_get0(const DSA_SIG *sig, const BIGNUM **pr, const BIGNUM **ps);
14 int DSA_SIG_set0(DSA_SIG *sig, BIGNUM *r, BIGNUM *s);
18 DSA_SIG_new() allocates and initializes a B<DSA_SIG> structure.
20 DSA_SIG_free() frees the B<DSA_SIG> structure and its components. The
21 values are erased before the memory is returned to the system.
23 DSA_SIG_get0() returns internal pointers to the B<r> and B<s> values contained
26 The B<r> and B<s> values can be set by calling DSA_SIG_set0() and passing the
27 new values for B<r> and B<s> as parameters to the function. Calling this
28 function transfers the memory management of the values to the DSA_SIG object,
29 and therefore the values that have been passed in should not be freed directly
30 after this function has been called.
34 If the allocation fails, DSA_SIG_new() returns B<NULL> and sets an
35 error code that can be obtained by
36 L<ERR_get_error(3)>. Otherwise it returns a pointer
37 to the newly allocated structure.
39 DSA_SIG_free() returns no value.
41 DSA_SIG_set0() returns 1 on success or 0 on failure.
