GSS_INQUIRE_MECHS_FOR_NAME(3) FreeBSD Library Functions Manual (prm)
NAME gss_inquire_mechs_for_name - List mechanisms that support the specified name-type
SYNOPSIS #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);
DESCRIPTION Returns the set of mechanisms supported by the GSS-API implementation that may be able to process the specified name.
Each mechanism returned will recognize at least one element within the name. It is permissible for this routine to be implemented within a mechanism-independent GSS-API layer, using the type information contained within the presented name, and based on registration information provided by individual mechanism implementations. This means that the returned mech_types set may indicate that a particular mechanism will understand the name when in fact it would refuse to accept the name as input to gss_canonicalize_name(), gss_init_sec_context(), gss_acquire_cred() or gss_add_cred() (due to some property of the specific name, as opposed to the name type). Thus this routine should be used only as a pre-filter for a call to a subsequent mechanism-specific routine.
PARAMETERS minor_status Mechanism specific status code.
input_name The name to which the inquiry relates.
mech_types 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().
RETURN VALUES GSS_S_COMPLETE Successful completion
GSS_S_BAD_NAME The input_name parameter was ill-formed
