.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\f(CW\*(C`GSSAPI::Status\*(C'\fR objects are returned by most other \s-1GSSAPI\s0 operations.
Such statuses consist of a \s-1GSSAPI\s0 generic code and, for most
operations, a mechanism specific code.  These numeric codes can be
accessed via the methods \f(CW\*(C`major\*(C'\fR and \f(CW\*(C`minor\*(C'\fR.  The standard textual
messages that go with the current status can be obtained via the
\&\f(CW\*(C`generic_message\*(C'\fR and \f(CW\*(C`specific_message\*(C'\fR methods.  Each of these
returns a list of text which should presumably be displayed in
order.
.PP
The generic code part of a GSSAPI::Status is composed of three
subfields that can be accessed with the \f(CW\*(C`GSS_CALLING_ERROR\*(C'\fR,
\&\f(CW\*(C`GSS_ROUTINE_ERROR\*(C'\fR, and \f(CW\*(C`GSS_SUPPLEMENTARY_INFO\*(C'\fR functions.  The
returned values can be compared against the constants whose names
start with \f(CW\*(C`GSS_S_\*(C'\fR if your code wants to handle particular errors
itself.  The \f(CW\*(C`GSS_ERROR\*(C'\fR function returns true if and only if the
given generic code contains neither a calling error nor a routine
error.
.PP
When evaluated in a boolean context, a \f(CW\*(C`GSSAPI::Status\*(C'\fR object
will be true if and only if the major status code is \f(CW\*(C`GSS_S_COMPLETE\*(C'\fR.
.PP
When evaluated in a string contect, a \f(CW\*(C`GSSAPI::Status\*(C'\fR object will
return the generic and specific messages all joined together with
newlines.  This may or may not make \f(CW\*(C`die $status\*(C'\fR work usefully.
.SH "BUGS"
.IX Header "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.
