GSS_PROCESS_CONTEXT_TOKEN(3)					Programmer's Manual				      GSS_PROCESS_CONTEXT_TOKEN(3)

NAME

     gss_process_context_token -- Process a token on a security context from a peer application

SYNOPSIS

     #include <gssapi/gssapi.h>

     OM_uint32
     gss_process_context_token(OM_uint32 *minor_status, const gss_ctx_id_t context_handle, const gss_buffer_t token_buffer);

DESCRIPTION

     Provides a way to pass an asynchronous token to the security service.  Most context-level tokens are emitted and processed synchronously by
     gss_init_sec_context() and gss_accept_sec_context(), and the application is informed as to whether further tokens are expected by the
     GSS_C_CONTINUE_NEEDED major status bit.  Occasionally, a mechanism may need to emit a context-level token at a point when the peer entity is
     not expecting a token.  For example, the initiator's final call to gss_init_sec_context() may emit a token and return a status of
     GSS_S_COMPLETE, but the acceptor's call to gss_accept_sec_context() may fail.  The acceptor's mechanism may wish to send a token containing
     an error indication to the initiator, but the initiator is not expecting a token at this point, believing that the context is fully estab-
     lished.  gss_process_context_token() provides a way to pass such a token to the mechanism at any time.

PARAMETERS

     minor_status    Mechanism specific status code.

     context_handle  Context handle of context on which token is to be processed.

     token_buffer    Token to process.

RETURN VALUES

     GSS_S_COMPLETE	    Successful completion

     GSS_S_DEFECTIVE_TOKEN  Indicates that consistency checks performed on the token failed

     GSS_S_NO_CONTEXT	    The context_handle did not refer to a valid context
