=pod =head1 NAME DSA_SIG_new, DSA_SIG_free - allocate and free DSA signature objects =head1 SYNOPSIS #include <openssl/dsa.h> DSA_SIG *DSA_SIG_new(void); void DSA_SIG_free(DSA_SIG *a); =head1 DESCRIPTION DSA_SIG_new() allocates and initializes a B<DSA_SIG> structure. DSA_SIG_free() frees the B<DSA_SIG> structure and its components. The values are erased before the memory is returned to the system. =head1 RETURN VALUES If the allocation fails, DSA_SIG_new() returns B<NULL> and sets an error code that can be obtained by L<ERR_get_error(3)|ERR_get_error(3)>. Otherwise it returns a pointer to the newly allocated structure. DSA_SIG_free() returns no value. =head1 SEE ALSO L<dsa(3)|dsa(3)>, L<ERR_get_error(3)|ERR_get_error(3)>, L<DSA_do_sign(3)|DSA_do_sign(3)> =head1 HISTORY DSA_SIG_new() and DSA_SIG_free() were added in OpenSSL 0.9.3. =cut
