5 DSA_new, DSA_free - allocate and free DSA objects
9 #include <openssl/dsa.h>
13 void DSA_free(DSA *dsa);
17 DSA_new() allocates and initializes a B<DSA> structure. It is equivalent to
18 calling DSA_new_method(NULL).
20 DSA_free() frees the B<DSA> structure and its components. The values are
21 erased before the memory is returned to the system.
25 If the allocation fails, DSA_new() returns B<NULL> and sets an error
26 code that can be obtained by
27 L<ERR_get_error(3)|ERR_get_error(3)>. Otherwise it returns a pointer
28 to the newly allocated structure.
30 DSA_free() returns no value.

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