The parameter descriptions for gss_inquire_cred() follow:
Mechanism specific status code.
Handle that refers to the target credential. Specify GSS_C_NO_CREDENTIAL to inquire about the default initiator principal.
Name of the identity asserted by the credential. Any storage associated with this name should be freed by the application after use by a call to gss_release_name(3GSS).
Number of seconds for which the credential remains valid. If the credential has expired, this parameter will be set to zero. Specify NULL if the parameter is not required.
Flag that indicates how a credential is used. The cred_usage parameter may contain one of the following values: GSS_C_INITIATE, GSS_C_ACCEPT, or GSS_C_BOTH. Specify NULL if this parameter is not required.
Set of mechanisms supported by the credential. Storage for the returned OID-set must be freed by the application after use by a call to gss_release_oid_set(3GSS). Specify NULL if this parameter is not required.
Use the gss_inquire_cred() function to obtain information about a credential.
The gss_inquire_cred() function can return the following status codes:
The referenced credentials could not be accessed.
The referenced credentials were invalid.
The referenced credentials have expired. If the lifetime parameter was not passed as NULL, it will be set to 0.
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.
