cc [ flag... ] file... -lgss [ library... ] #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);
The gss_process_context_token() function 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 might 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() might fail. The acceptor's mechanism might want 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.
This function is provided for compatibility with the GSS-API version 1. Because gss_delete_sec_context() no longer returns a valid output_token to be sent to gss_process_context_token(), applications using a newer version of the GSS-API do not need to rely on this function.
The parameter descriptions for gss_process_context_token() are as follows: minor_status
A mechanism-specific status code.
Context handle of context on which token is to be processed.
Token to process.
gss_process_context_token() returns one of the following status codes: GSS_S_COMPLETE
Successful completion.
Indicates that consistency checks performed on the token failed.
The context_handle did not refer to a valid context.
The underlying mechanism detected an error for which no specific GSS status code is defined. The mechanism-specific status code reported by means of the minor_status parameter details the error condition.
