NAME

GSSAPI::Status - methods for handlings GSSAPI statuses

SYNOPSIS

  use GSSAPI;
  
  $status = GSSAPI::Status->new(GSS_S_COMPLETE, 0);

  if (GSS_ERROR($status->major)) {
    die "a horrible death";
  }
  if (! $status) {                      # another way of writing the above
    die "a horrible death";
  }

  $status = $some_GSSAPI->someop($args1, etc);
  if ($status) {
    foreach ($status->generic_message, $status->specific_message) {
      print "GSSAPI error: $_\n";
    }
    die "help me";
  }

DESCRIPTION

GSSAPI::Status objects are returned by most other GSSAPI operations. Such statuses consist of a GSSAPI generic code and, for most operations, a mechanism specific code. These numeric codes can be accessed via the methods major and minor. The standard textual messages that go with the current status can be obtained via the generic_message and specific_message methods. Each of these returns a list of text which should presumably be displayed in order.

The generic code part of a GSSAPI::Status is composed of three subfields that can be accessed with the GSS_CALLING_ERROR, GSS_ROUTINE_ERROR, and GSS_SUPPLEMENTARY_INFO functions. The returned values can be compared against the constants whose names start with GSS_S_ if your code wants to handle particular errors itself. The GSS_ERROR function returns true if and only if the given generic code contains neither a calling error nor a routine error.

When evaluated in a boolean context, a GSSAPI::Status object will be true if and only if the major status code is GSS_S_COMPLETE.

When evaluated in a string contect, a GSSAPI::Status object will return the generic and specific messages all joined together with newlines. This may or may not make die $status work usefully.

BUGS

The base objects are currently implmented as a blessed C structure containing the major and minor status codes. It should probably be a blessed array or hash instead, thereby cutting down on the amount of C code involved and making it more flexible.
