DSA_SIG_new(3)                      OpenSSL                     DSA_SIG_new(3)




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.  If the
       argument is NULL, nothing is done.

       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.
