new
        my $probe = FFI::Probe->new(%args);

       Creates a new instance.

       log Path to a log or file handle to write to.

       data_filename
           Path to a file which will be used to store/cache results.

       This class provides an interface for probing for system capabilities.  It is used internally as part of
       the FFI::Platypus build process, but it may also be useful for extensions that use Platypus as well.

check_header
        my $bool = $probe->check_header($header);

       Checks that the given C header file is available.  Stores the result, and returns a true/false value.

   check_cppcheck_eval
        my $bool = $probe>check_eval(%args);

       headers
           Any additional headers.

       decl
           Any C declarations that need to be made before the "dlmain" function.

       stmt
           Any C statements that should be made before the evaluation.

       eval
           Any evaluations that should be returned.

   checkcheck_type_int
        my $type = $probe->check_type_int($type);

   check_type_enum
        my $type = $probe->check_type_enum;

   check_type_enum
        my $type = $probe->check_type_enum;

   check_type_float
        my $type = $probe->check_type_float($type);

   check_type_pointer
        my $type = $probe->check_type_pointer;

   set
        $probe->set(@key, $value);

       Used internally to store a value.

   save
        $probe->save;

       Saves the values already detected.

   data
        my $data = $probe->data;

       Returns a hashref of the data already detected.

   log
        $probe->log($string);

       Sends the given string to the log.

   log_code
        $prbe->log_code($string);

       Sends the given multi-line code block to the log.

   template
        my $template = $probe->template;

       Returns the C code template used for "check_eval" and other "check_" methods.

        my $probe = FFI::Probe->new;
