1=pod 2 3=head1 NAME 4 5DSA_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 17DSA_new() allocates and initializes a B<DSA> structure. It is equivalent to 18calling DSA_new_method(NULL). 19 20DSA_free() frees the B<DSA> structure and its components. The values are 21erased before the memory is returned to the system. 22 23=head1 RETURN VALUES 24 25If the allocation fails, DSA_new() returns B<NULL> and sets an error 26code that can be obtained by 27L<ERR_get_error(3)|ERR_get_error(3)>. Otherwise it returns a pointer 28to the newly allocated structure. 29 30DSA_free() returns no value. 31 32=head1 SEE ALSO 33 34L<dsa(3)|dsa(3)>, L<ERR_get_error(3)|ERR_get_error(3)>, 35L<DSA_generate_parameters(3)|DSA_generate_parameters(3)>, 36L<DSA_generate_key(3)|DSA_generate_key(3)> 37 38=head1 HISTORY 39 40DSA_new() and DSA_free() are available in all versions of SSLeay and OpenSSL. 41 42=cut 43
