PropertyHandle :: Check - Check property handle
The function checks whether a property handle is valid and opened.
Usually property handles are opened on demand, i.e. when access to any database source is required. After opening a property handle a structure definition is available and access is possible in principle. Passing iniopt=YES (true) to the function will initialize the property handle, when not yet being initialized.
If the property handle is invalid or not opened the function returns YES, otherwise NO.
Return value: Success ( logical )
