1 =pod 2 3 =head1 NAME 4 5 DSA_new, DSA_free - allocate and free DSA objects 6 7 =head1 SYNOPSIS 8 9 #include <openssl/dsa.h> 10 11 DSA* DSA_new(void); 12 13 void DSA_free(DSA *dsa); 14 15 =head1 DESCRIPTION 16 17 DSA_new() allocates and initializes a B<DSA> structure. It is equivalent to 18 calling DSA_new_method(NULL). 19 20 DSA_free() frees the B<DSA> structure and its components. The values are 21 erased before the memory is returned to the system. 22 If B<dsa> is NULL nothing is done. 23 24 =head1 RETURN VALUES 25 26 If the allocation fails, DSA_new() returns B<NULL> and sets an error 27 code that can be obtained by 28 L<ERR_get_error(3)>. Otherwise it returns a pointer 29 to the newly allocated structure. 30 31 DSA_free() returns no value. 32 33 =head1 SEE ALSO 34 35 L<DSA_new(3)>, L<ERR_get_error(3)>, 36 L<DSA_generate_parameters(3)>, 37 L<DSA_generate_key(3)> 38 39 =head1 COPYRIGHT 40 41 Copyright 2000-2016 The OpenSSL Project Authors.
