# EOS_PT_REGIONINFO

This function returns information about a subsetted area of interest for a particular fieldlist.

## Examples

In this example, we get the size of the subsetted area of interest defined in EOS_PT_DEFBOXREGION from the Longitude and Latitude fields:

status = EOS_PT_REGIONINFO(pointID, regionID, 0, "Longitude, $

Latitude",size)

## Syntax

Result = EOS_PT_REGIONINFO(pointID, regionID, level, fieldlist, size)

## Return Value

Returns SUCCEED (0) if successful and FAIL (–1) otherwise.

## Arguments

### pointID

Point id (long).

### regionID

Region id (long) returned by EOS_PT_DEFBOXREGION.

### level

Point level (0-based long).

### fieldlist

List of fields (sting) to extract.

### size

A named variable that will contain the size in bytes (long) of subset period.
