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

38 DSA_SIG_new() and DSA_SIG_free() were added in OpenSSL 0.9.3.
