## Declaration

Source position: line 0

`function GetInt64Prop(`
`Instance: TObject;`
`PropInfo: PPropInfo`
`):Int64; function GetInt64Prop(`
`Instance: TObject;`
`const PropName: string`
`):Int64;`

## Description

Remark: | Publishing of Int64 properties is not yet supported by Free Pascal. This function is provided for Delphi compatibility only at the moment.

GetInt64Prop returns the value of the property of type Int64 that is described by PropInfo or with name Propname for the object Instance.

## Errors

No checking is done whether Instance is non-nil, or whether PropInfo describes a valid Int64 property of Instance. Specifying an invalid property name in PropName will result in an EPropertyError exception
