NAME
       gss_inquire_mechs_for_name - list mechanisms that support the specified name-type

SYNOPSIS
       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);

DESCRIPTION
       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  registra-
       tion  information  provided by individual mechanisms.  This means that the mech_types set returned by the function may indicate that a par-
       ticular mechanism will understand the name, when in fact the mechanism  would  refuse  to  accept  the  name  as  input	to  gss_canonical-
       ize_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.

PARAMETERS
       The parameter descriptions for gss_inquire_mechs_for_name() follow in alphabetical order:

       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(3GSS).

ERRORS
       The gss_inquire_mechs_for_name() function may return the following status codes:

       GSS_S_COMPLETE	     Successful completion.

       GSS_S_BAD_NAME	     The input_name parameter was ill-formed.

       GSS_S_BAD_NAMETYPE    The input_name parameter contained an invalid or unsupported type of name.

       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.
