acceptor_lifetime
The number of seconds that the credential is capable of accepting security contexts under the specified mechanism. If the credential can no longer be used to accept contexts, or if the credential usage for this mechanism is GSS_C_INITIATE, this parameter will be set to 0. Specify NULL if this parameter is not required.
cred_handle
A handle that refers to the target credential. Specify GSS_C_NO_CREDENTIAL to inquire about the default initiator principal.
cred_usage
How the credential may be used with the specified mechanism. 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.
initiator_lifetime
The number of seconds that the credential is capable of initiating security contexts under the specified mechanism. If the credential can no longer be used to initiate contexts, or if the credential usage for this mechanism is GSS_C_ACCEPT, this parameter will be set to 0. Specify NULL if this parameter is not required.
mech_type
The mechanism for which the information should be returned.
minor_status
A mechanism specific status code.
name
The name whose identity the credential asserts. Any storage associated with this name must be freed by the application after use by a call to gss_release_name(3GSS).
The gss_inquire_cred_by_mech() function obtains per-mechanism information about a credential.
The gss_inquire_cred_by_mech() function can return the following status codes:
GSS_S_COMPLETE
Successful completion.
GSS_S_CREDENTIALS_EXPIRED
The credentials cannot be added because they have expired.
GSS_S_DEFECTIVE_CREDENTIAL
The referenced credentials are invalid.
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.
GSS_S_NO_CRED
The referenced credentials cannot be accessed.
GSS_S_UNAVAILABLE
The gss_inquire_cred_by_mech() function is not available for the specified mechanism type.
