rpc_gss_get_mechanisms(), rpc_gss_get_mech_info(), rpc_gss_get_versions(), rpc_gss_is_installed() — get information on mechanisms and RPC version
These "convenience functions" return information on available security

Otherwise, it returns a null-terminated list of character strings of
supported Quality of Protections (QOPs) for this mechanism.
NULL or empty list implies only that the default QOP is available and can be
specified to routines that need to take a QOP string parameter as NULL
or as an empty string.
