 GSS_INQUIRE_MECHS_FOR_NAME 3GSS "Jan 15, 2003"
 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 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.
 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.
