Informix DataBlade API Programmer's Manual DataBlade API Function Descriptions

The mi_fp_getrow() accessor function obtains the row structure that is associated with the user-defined routine from its MI_FPARAM structure.

MI_ROW *mi_fp_getrow(fparam_ptr)

MI_FPARAM *fparam_ptr;

fparam_ptr

is a pointer to the associated MI_FPARAM structure.

Valid in Client LIBMI Application?	Valid in User-Defined Routine?
No	Yes

The mi_fp_getrow() function obtains the row structure for the user-defined routine that is associated with the fparam_ptr MI_FPARAM structure. This function is only valid within an assign(), destroy(), or import support function for an opaque data type that contains smart large objects and for multirepresentational opaque types. The database server automatically obtains the row structure before it executes the assign(), destroy(), or import function of an opaque data type, and stores it in the MI_FPARAM structure.

With the mi_fp_getrow() function, you can implement:

• delayed creation of a smart large object within the assign() support function.

This function can obtain the row structure into which you want to store the opaque type.

• delayed removal of a smart large object within the destroy() support function.

This function can obtain the row structure from which you want to remove the opaque type.

Important: The mi_fp_getrow() function is valid only when called from within an assign(), destroy(), or import support function of an opaque data type. Outside the context of an assign() or destroy() function, mi_fp_getrow() always returns a NULL-valued pointer. For more information, see the description of the mi_lo_colinfo_by_ids() function.

See the descriptions of the following functions: mi_fp_getcolid() and mi_lo_colinfo_by_ids().
