Informix DataBlade API Programmer's Manual DataBlade API Function Descriptions

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

void mi_fp_setarglen(fparam_ptr, arg_pos, arg_len)

MI_FPARAM *fparam_ptr;

mi_integer arg_pos;

mi_integer arg_len;

fparam_ptr	is a pointer to the associated MI_FPARAM structure.
arg_pos	is the index position into the argument-length array for the argument whose length you want to set.
arg_len	is the length, in bytes, to set for the arg_pos+1 argument.

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

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

mi_integer my_func(...., fparam1)
	

	MI_FPARAM *fparam1;
{
	

	mi_fp_setarglen(fparam1, 2, 4);

None.
