DSA_SIG_new, DSA_SIG_free - allocate and free DSA signature objects
#include <openssl/dsa.h> DSA_SIG *DSA_SIG_new(void); void DSA_SIG_free(DSA_SIG *a);
DSA_SIG_new() allocates and initializes a 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 allocation fails, DSA_SIG_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_SIG_free() returns no value.
DSA_SIG_new() and DSA_SIG_free() were added in OpenSSL 0.9.3.
