Informix DataBlade API Programmer's Manual DataBlade API Function Descriptions

The mi_fp_usr_fparam() accessor function determines whether the database server or the developer has allocated the specified MI_FPARAM structure.

mi_boolean mi_fp_usr_fparam (MI_FPARAM 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?
Yes	Yes

The Fastpath interface uses an MI_FPARAM structure to hold information about the UDR or cast function to execute. This MI_FPARAM structure can be allocated in one of two ways:

• By the Fastpath look-up functions (mi_cast_get(), mi_func_desc_by_typeid(), mi_routine_get(), mi_routine_get_by_typeid(), or mi_td_cast_get()) as part of the function descriptor for the routine to execute
• By the developer with the mi_fparam_allocate() or mi_fparam_copy() function

The mi_fp_usr_fparam() function determines which of these two methods was used to allocate the MI_FPARAM structure that fparam_ptr references.

See the descriptions of the following functions: mi_cast_get(), mi_fparam_allocate(), mi_fparam_copy(), mi_fparam_free() mi_func_desc_by_typeid(), mi_routine_exec(), mi_routine_get(), mi_routine_get_by_typeid(), and mi_td_cast_get().
