DSA_SIG_NEW(3ossl) OpenSSL DSA_SIG_NEW(3ossl)
NAME
DSA_SIG_get0, DSA_SIG_set0, DSA_SIG_new, DSA_SIG_free - allocate and
free DSA signature objects
SYNOPSIS
#include <openssl/dsa.h>
DSA_SIG *DSA_SIG_new(void);
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);
DESCRIPTION
DSA_SIG_new() allocates an empty DSA_SIG structure.
DSA_SIG_free() frees the 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 r and s values
contained in sig.
The r and s values can be set by calling DSA_SIG_set0() and passing the
new values for r and 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.
RETURN VALUES
If the allocation fails, DSA_SIG_new() returns NULL and sets an error
code that can be obtained by 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.
