Ft_service_class

• FT_SC_UNCONSTRAINED, FT_SC_TRANSFER and

FT_SC_ACCESS

• FT_SC_UNCONSTRAINED, FT_SC_MANAGEMENT,

FT_SC_TRANSFER, and FT_SC_TRANSFER_AND_MGMT

• FT_SC_UNCONSTRAINED, FT_SC_MANAGEMENT,

FT_SC_TRANSFER, FT_SC_ACCESS, and

FT_SC_TRANSFER_AND_MGT

• You must negotiate Ft_service_class when calling ft_connect().

• Ft_service_class deﬁnes the mandatory and optional

Ft_functional_units. Set these restrictions using the deﬁned

constants. Each FT_SC_XXX dictates which FT_FU_XXX

(Ft_functional_unit) deﬁned constants are mandatory and optional

(as noted in the following table).

EXAMPLE: On ft_connect(), if you specify the FT_SC_TRANSFER_AND_MGT

service_class,

• You must specify FT_FU_GROUPING and FT_FU_LTD_MGMT

functional_units,

• You must specify either or both FT_FU_READ and FT_FU_WRITE,

• You can optionally specify FT_FU_ENH_MGMT, and

• You cannot specify FT_FU_FILE ACCESS.
