#include <openssl/dsa.h>
DSA_SIG *DSA_SIG_new(void);
void DSA_SIG_free(DSA_SIG *a);
void DSA_SIG_free(DSA_SIG *a);
void DSA_SIG_get0(const DSA_SIG *sig, const BIGNUM **pr, const BIGNUM **ps);
int DSA_SIG_set0(DSA_SIG *sig, BIGNUM *r, BIGNUM *s);
=head1 DESCRIPTION
DSA_SIG_new() allocates and initializes a B<DSA_SIG> structure.
DSA_SIG_new() allocates an empty B<DSA_SIG> structure.
DSA_SIG_free() frees the B<DSA_SIG> structure and its components. The
values are erased before the memory is returned to the system.
DSA_SIG_get0() returns internal pointers to the B<r> and B<s> values contained
in B<sig>.
The B<r> and B<s> values can be set by calling DSA_SIG_set0() and passing the
new values for B<r> and B<s> as parameters to the function. Calling this
function transfers the memory management of the values to the DSA_SIG object,
and therefore the values that have been passed in should not be freed directly
after this function has been called.
=head1 RETURN VALUES
If the allocation fails, DSA_SIG_new() returns B<NULL> and sets an
error code that can be obtained by
L<ERR_get_error(3)|ERR_get_error(3)>. Otherwise it returns a pointer
L<ERR_get_error(3)>. Otherwise it returns a pointer
to the newly allocated structure.
DSA_SIG_free() returns no value.
DSA_SIG_set0() returns 1 on success or 0 on failure.
