If the context was established using anonymous authentication, and if the application invoking gss_inquire_context is the context acceptor, an anonymous name will be returned. Storage associated with this name must be freed by the application after use with a call to \fBgss_release_name()\fP. Specify NULL if not required. .IP "gss_name_t * targ_name" 12 (gss_name_t, modify, optional) The name of the context acceptor. Storage associated with this name must be freed by the application after use with a call to \fBgss_release_name()\fP. If the context acceptor did not authenticate itself, and if the initiator did not specify a target name in its call to \fBgss_init_sec_context()\fP, the value GSS_C_NO_NAME will be returned. Specify NULL if not required. .IP "OM_uint32 * lifetime_rec" 12 (Integer, modify, optional) The number of seconds for which the context will remain valid. If the context has expired, this parameter will be set to zero. If the implementation does not support context expiration, the value GSS_C_INDEFINITE will be returned. Specify NULL if not required. .IP "gss_OID * mech_type" 12 (gss_OID, modify, optional) The security mechanism providing the context. The returned OID will be a pointer to static storage that should be treated as read\-only by the application; in particular the application should not attempt to free it. Specify NULL if not required. .IP "OM_uint32 * ctx_flags" 12 (bit\-mask, modify, optional) Contains various independent flags, each of which indicates that the context supports (or is expected to support, if ctx_open is false) a specific service option. If not needed, specify NULL. Symbolic names are provided for each flag, and the symbolic names corresponding to the required flags should be logically\-ANDed with the ret_flags value to test whether a given option is supported by the context. See below for the flags. .IP "int * locally_initiated" 12 (Boolean, modify) Non\-zero if the invoking application is the context initiator. Specify NULL if not required. .IP "int * open" 12 (Boolean, modify) Non\-zero if the context is fully established; Zero if a context\-establishment token is expected from the peer application. Specify NULL if not required. .SH "DESCRIPTION" Obtains information about a security context. The caller must already have obtained a handle that refers to the context, although the context need not be fully established. The `ctx_flags` values: `GSS_C_DELEG_FLAG`:: \- True \- Credentials were delegated from the initiator to the acceptor. \- False \- No credentials were delegated. `GSS_C_MUTUAL_FLAG`:: \- True \- The acceptor was authenticated to the initiator. \- False \- The acceptor did not authenticate itself. `GSS_C_REPLAY_FLAG`:: \- True \- replay of protected messages will be detected. \- False \- replayed messages will not be detected. `GSS_C_SEQUENCE_FLAG`:: \- True \- out\-of\-sequence protected messages will be detected. \- False \- out\-of\-sequence messages will not be detected. `GSS_C_CONF_FLAG`:: \- True \- Confidentiality service may be invoked by calling gss_wrap routine. \- False \- No confidentiality service (via gss_wrap) available. gss_wrap will provide message encapsulation, data\-origin authentication and integrity services only. `GSS_C_INTEG_FLAG`:: \- True \- Integrity service may be invoked by calling either gss_get_mic or gss_wrap routines. \- False \- Per\-message integrity service unavailable. `GSS_C_ANON_FLAG`:: \- True \- The initiator's identity will not be revealed to the acceptor. The src_name parameter (if requested) contains an anonymous internal name. \- False \- The initiator has been authenticated normally. `GSS_C_PROT_READY_FLAG`:: \- True \- Protection services (as specified by the states of the GSS_C_CONF_FLAG and GSS_C_INTEG_FLAG) are available for use. \- False \- Protection services (as specified by the states of the GSS_C_CONF_FLAG and GSS_C_INTEG_FLAG) are available only if the context is fully established (i.e. if the open parameter is non\-zero). `GSS_C_TRANS_FLAG`:: \- True \- The resultant security context may be transferred to other processes via a call to \fBgss_export_sec_context()\fP. \- False \- The security context is not transferable. .SH "RETURN VALUE" `GSS_S_COMPLETE`: Successful completion. `GSS_S_NO_CONTEXT`: The referenced context could not be accessed. .SH "REPORTING BUGS" Report bugs to .
