NAME

6       DSA_SIG_get0, DSA_SIG_set0, DSA_SIG_new, DSA_SIG_free - allocate and
7       free DSA signature objects
8

SYNOPSIS

10        #include <openssl/dsa.h>
11
12        DSA_SIG *DSA_SIG_new(void);
13        void DSA_SIG_free(DSA_SIG *a);
14        void DSA_SIG_get0(const DSA_SIG *sig, const BIGNUM **pr, const BIGNUM **ps);
15        int DSA_SIG_set0(DSA_SIG *sig, BIGNUM *r, BIGNUM *s);
16

DESCRIPTION

18       DSA_SIG_new() allocates an empty DSA_SIG structure.
19
20       DSA_SIG_free() frees the DSA_SIG structure and its components. The
21       values are erased before the memory is returned to the system.
22
23       DSA_SIG_get0() returns internal pointers to the r and s values
24       contained in sig.
25
26       The r and s values can be set by calling DSA_SIG_set0() and passing the
27       new values for r and s as parameters to the function. Calling this
28       function transfers the memory management of the values to the DSA_SIG
29       object, and therefore the values that have been passed in should not be
30       freed directly after this function has been called.
31

RETURN VALUES

33       If the allocation fails, DSA_SIG_new() returns NULL and sets an error
34       code that can be obtained by ERR_get_error(3). Otherwise it returns a
35       pointer to the newly allocated structure.
36
37       DSA_SIG_free() returns no value.
38
39       DSA_SIG_set0() returns 1 on success or 0 on failure.
