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 )
