Informix DataBlade API Programmer's Manual DataBlade API Function Descriptions

The mi_fp_argtype() accessor function obtains the type identifier for the data type of an argument of a user-defined routine from its associated MI_FPARAM structure.

MI_TYPEID *mi_fp_argtype(fparam_ptr, arg_pos)

MI_FPARAM *fparam_ptr;

mi_integer arg_pos;

fparam_ptr	is a pointer to the associated MI_FPARAM structure.
arg_pos	is the index position into the argument-type array for the argument whose type identifier you want.

Valid in Client LIBMI Application?	Valid in User-Defined Routine?
Yes	Yes

The mi_fp_argtype() function obtains the type identifier (MI_TYPEID) of the routine argument at position arg_pos from the MI_FPARAM structure that fparam_ptr references. The type identifier is an integer value that indicates a particular data type. The MI_FPARAM structure stores information about the type identifiers of routine arguments in the zero-based argument-type array. To obtain information about the nth argument, use an arg_pos value of n-1. For example, the following call to mi_fp_argtype() obtains the type identifier for the third argument of the my_func() UDR, with which fparam1 is associated:

mi_integer my_func(...., fparam1)
	

	MI_FPARAM *fparam1;
{
	MI_TYPEID *arg_type;
	

	arg_type = mi_fp_argtype(fparam1, 2);

See the descriptions of the following functions: mi_fp_argisnull(), mi_fp_arglen(), mi_fp_argprec(), mi_fp_argscale(), mi_fp_rettype(), mi_fp_setargtype(), and mi_fp_setrettype().
