gss_process_context_token(3)

NAME
gss_process_context_token - API function

SYNOPSIS
#include <gss.h>

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

ARGUMENTS

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

const gss_ctx_id_t context_handle
    (gss_ctx_id_t, read) Context handle of context on
      which token is to be processed

const gss_buffer_t token_buffer
    (buffer, opaque, read) Token to process.

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 established. Gss_process_context_token provides a way to pass such a token to the mechanism at any time.

RETURN VALUE
`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.
