Use the a_v4_extfn_describe_udf_type enumerated type to select the logical property the UDF retrieves or sets.
typedef enum a_v4_extfn_describe_udf_type { EXTFNAPIV4_DESCRIBE_UDF_NUM_PARMS, EXTFNAPIV4_DESCRIBE_UDF_LAST } a_v4_extfn_describe_udf_type;
Member | Description |
---|---|
EXTFNAPIV4_DESCRIBE_UDF_NUM_PARMS | The number of parameters supplied to the UDF. |
EXTFNAPIV4_DESCRIBE_UDF_LAST | Out-of-band value. |
The a_v4_extfn_proc_context.describe_udf_get() method is used by the UDF to retrieve properties, and the a_v4_extfn_proc_context.describe_udf_set() method is used by the UDF to set properties about the UDF as a whole. The a_v4_extfn_describe_udf_type enumerator selects the logical property the UDF retrieves or sets.
