DSA_new, DSA_free - allocate and free DSA objects
#include <openssl/dsa.h>
DSA* DSA_new(void);
void DSA_free(DSA *dsa);
DSA_new() allocates and initializes a DSA structure. It is equivalent to
calling DSA_new_method(NULL).
DSA_free() frees the DSA structure and its components. The values are
erased before the memory is returned to the system.
If the allocation fails, DSA_new() returns NULL and sets an error
code that can be obtained by
ERR_get_error. Otherwise it returns a pointer
to the newly allocated structure.
DSA_free() returns no value.

DSA_new() and DSA_free() are available in all versions of SSLeay and OpenSSL.
