The gss_import_sec_context() function allows a process to import a security context established by another process. A given interprocess token can be imported only once. See gss_export_sec_context(3GSS).

The parameter descriptions for gss_import_sec_context() are as follows:

minor_status

A mechanism-specific status code.

interprocess_token

Token received from exporting process.

context_handle

Context handle of newly reactivated context. Resources associated with this context handle must be released by the application after use with a call to gss_delete_sec_context(3GSS).

gss_import_sec_context() returns one of the following status codes:

GSS_S_COMPLETE

Successful completion.

GSS_S_NO_CONTEXT

The token did not contain a valid context reference.

GSS_S_DEFECTIVE_TOKEN

The token was invalid.

GSS_S_UNAVAILABLE

The operation is unavailable.

GSS_S_UNAUTHORIZED

Local policy prevents the import of this context by the current process.

GSS_S_FAILURE

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.
