NAME

DSA_new, DSA_free — allocate and free DSA objects

Synopsis

#include <openssl/dsa.h> 
DSA* DSA_new(void);
void DSA_free(DSA *dsa);

DESCRIPTION

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.

RETURN VALUES

If the allocation fails, DSA_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_free() returns no value.

SEE ALSO

HISTORY

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