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.

       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.
