       gss_wrap_size_limit - API function


       #include <gss.h>

       OM_uint32 gss_wrap_size_limit(OM_uint32 * minor_status, const gss_ctx_id_t context_handle,
       int   conf_req_flag,   gss_qop_t   qop_req,   OM_uint32   req_output_size,   OM_uint32   *


       OM_uint32 * minor_status
                   (Integer, modify) Mechanism specific status code.

       const gss_ctx_id_t context_handle
                   (gss_ctx_id_t, read) A handle that refers to the
                     security over which the messages will be sent.

       int conf_req_flag
                   (Boolean, read) Indicates whether gss_wrap will be
                     asked to apply confidentiality protection in addition to
                     integrity protection.  See the routine description for gss_wrap
                     for more details.

       gss_qop_t qop_req
                   (gss_qop_t, read) Indicates the level of protection that
                     gss_wrap will be asked to provide.  See the routine description
                     for gss_wrap for more details.

       OM_uint32 req_output_size
                   (Integer, read) The desired maximum size for
                     tokens emitted by gss_wrap.

       OM_uint32 * max_input_size
                   (Integer, modify) The maximum input message size
                     that may be presented to gss_wrap in order to guarantee that the
                     emitted token shall be no larger than req_output_size bytes.


       Allows an application to determine the maximum message size that, if presented to gss_wrap
       with the same conf_req_flag and  qop_req  parameters,  will  result  in  an  output  token
       containing no more than req_output_size bytes.

       This  call is intended for use by applications that communicate over protocols that impose
       a maximum message size.  It enables the application to fragment messages prior to applying

       GSS-API implementations are recommended but not required to detect invalid QOP values when
       gss_wrap_size_limit() is called. This routine guarantees only a maximum message size,  not
       the availability of specific QOP values for message protection.

       Successful  completion  of  this  call  does  not  guarantee that gss_wrap will be able to
       protect a message of length max_input_size bytes, since this ability  may  depend  on  the
       availability  of  system  resources  at the time that gss_wrap is called.  However, if the
       implementation itself imposes an upper limit  on  the  length  of  messages  that  may  be
       processed  by  gss_wrap,  the implementation should not return a value via max_input_bytes
       that is greater than this length.


       `GSS_S_COMPLETE`: Successful completion.

       `GSS_S_NO_CONTEXT`: The referenced context could not be accessed.

       `GSS_S_CONTEXT_EXPIRED`: The context has expired.

       `GSS_S_BAD_QOP`: The specified QOP is not supported by the mechanism.
