The permission mask is set at table creation and specifies a permission mask that determines the kind of access that users may acquire on subsequent opens. The mask is comprised of three components: owner permissions, group permissions and world permissions. With this structure, you are able to allow different users different levels of access to the file. The default permission mask is set to (O_ALL | GPF_READ | GPF_WRITE | WPF_READ | WPF_WRITE). To set the table permissions, use CTTable.SetPermission(). To retrieve the permission mask, use CTTable.GetPermission(). The valid permission mask values, defined in the TABLE_PERMS enum, are:
