mi_fp_funcstate()mi_fp_setfuncstate()
Pointer to a function-specific structure that holds state information during routine execution
mi_fp_request()
Indicates the operation being performed on this call to the routine in MI_FPARAM.
Values are: SET_INIT, SET_RETONE, SET_END, SET_INVALID
mi_fp_nargs()mi_fp_setnargs()
Number of arguments for routine in MI_FPARAM
mi_fp_arglen()mi_fp_setarglen()
Array that stores the length of each argument
mi_fp_argprec()mi_fp_setargprec()
Array that stores the precision of each argument
mi_fp_argscale()mi_fp_setargscale()
Array that stores the scale of each argument
mi_fp_argisnull()mi_fp_setargisnull()
Array that indicates if the nth+1 argument is null
mi_fp_argtype()mi_fp_setargtype()
Array that contains the data-type constants for each of the arguments of the routine in the MI_FPARAM structure
mi_fp_nrets()mi_fp_setnrets()
Number of return values for routine in MI_FPARAM (always 1 for C routines)
mi_fp_retlen()mi_fp_setretlen()
The length of return value
mi_fp_retprec()mi_fp_setretprec()
The precision of the return value
The scale of the return value
mi_fp_rettype()mi_fp_setrettype()
Data-type constant for nth+1 return value of routine in MI_FPARAM (n=0 for all C routines)
mi_fp_returnisnull()mi_fp_setreturnisnull()
MI_TRUE or MI_FALSE to indicate whether nth return value of routine in MI_FPARAM is null (n=0 for all C routines)
mi_fp_setisdone()
MI_TRUE or MI_FALSE to indicate whether function has finished returning rows of data
mi_fp_setfuncid()
Function ID of the routine in the MI_FPARAM structure
The MI_FPARAM structure allows you to save memory across function calls. The following types of DataBlade functions must accept an additional parameter that is a pointer to an MI_FPARAM structure when it needs to perform the following tasks:
