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.
