This routine returns the maximum number of bytes that can fit into a segment. For a peripheral like long line, it is the number of points that can fit in the input length times the size of a point plus the size of a line's overhead.

Inputs

The inputs for this function are:

scb

Pointer to a SCB

dt_id

Data type ID of peripheral object

result_dv

Pointer to an II_DATA_VALUE with the maximum size of the segment in the length field

Outputs

The outputs for this function are:

result_dv

Pointer to an II_DATA_VALUE that receives the underlying data type, the maximum length of the underlying data type, and the precision of the underlying data type.

Returns

II_STATUS
