Informix DataBlade API Programmer's Manual DataBlade API Function Descriptions

The mi_fp_setargscale() accessor function sets the scale of an argument of a user-defined routine in its associated MI_FPARAM structure.

void mi_fp_setargscale(fparam_ptr, arg_pos, arg_scale)

MI_FPARAM *fparam_ptr;

mi_integer arg_pos;

mi_integer arg_scale;

fparam_ptr	is a pointer to the associated MI_FPARAM structure.
arg_pos	is the index position into the argument-scale array for the argument whose scale you want to set.
arg_scale	is the integer scale, in number of digits, to set for the arg_pos+1 argument.

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

The mi_fp_setargscale() function sets the scale of the routine argument at position arg_pos in the MI_FPARAM structure that fparam_ptr references.

The scale is an attribute of the data type. The meaning of the scale depends on the associated data type, as the following table shows.

The MI_FPARAM structure stores information about the scale of routine arguments in the zero-based argument-scale array. To set information for the nth argument, use an arg_pos value of n-1. For example, the following call to mi_fp_setargscale() sets the scale for the third argument of the my_func() UDR, with which fparam1 is associated:

mi_integer my_func(...., fparam1)
	

	MI_FPARAM *fparam1;
{
	

	mi_fp_setargscale(fparam1, 2, 4);

None.

See the descriptions of the following functions: mi_fp_argscale(), mi_fp_setargisnull(), mi_fp_setarglen(), mi_fp_setargprec(), mi_fp_setargtype(), mi_fp_retscale(), and mi_fp_setretscale().
