cc [flag …] file… –lgss [library …] #include <gssapi/gssapi.h> OM_uint32 gss_inquire_mechs_for_name(OM_uint32 *minor_status, const gss_name_t input_name,gss_OID_set *mech_types);
The gss_inquire_mechs_for_name() function returns the set of mechanisms supported by the GSS-API that may be able to process the specified name. Each mechanism returned will recognize at least one element within the internal name.
Some implementations of the GSS-API may perform this test by checking nametype information contained within the passed name and registration information provided by individual mechanisms. This means that the mech_types set returned by the function may indicate that a particular mechanism will understand the name, when in fact the mechanism would refuse to accept the name as input to gss_canonicalize_name(3GSS), gss_init_sec_context(3GSS), gss_acquire_cred(3GSS), or gss_add_cred(3GSS), due to some property of the name itself rather than the name-type. Therefore, this function should be used only as a pre-filter for a call to a subsequent mechanism-specific function.
The parameter descriptions for gss_inquire_mechs_for_name() follow in alphabetical order:
Mechanism-specific status code.
The name to which the inquiry relates.
Set of mechanisms that may support the specified name. The returned OID set must be freed by the caller after use with a call to gss_release_oid_set(3GSS).
The gss_inquire_mechs_for_name() function may return the following status codes:
The input_name parameter was ill-formed.
The input_name parameter contained an invalid or unsupported type of name.
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.
