# EOS_PT_SIZEOF

This function returns information about specified fields in a point regardless of level.

## Examples

In this example, we return the size in bytes of the Label and Rainfall fields in the 2nd point defined in the EOS_PT_DEFLEVEL function:

size = EOS_PT_SIZEOF(pointID2, "Label,Rainfall", fldlevel)

## Syntax

Result = EOS_PT_SIZEOF(pointID, fieldlist, fldlevel)

## Return Value

Returns size in bytes of specified fields and FAIL (–1) otherwise.

## Arguments

### pointID

Point id (long) returned by EOS_PT_CREATE or EOS_PT_ATTACH.

### fieldlist

Field names (string).

### fldlevel

A named variable that will contain the level number (long) of each field.
