LSRolesMask

Specify the desired role or roles for an application to claim with respect to an item or family of items.

Declaration

struct LSRolesMask

Overview

This bit mask is passed to functions that find the preferred application for a given item or family of items (LSGetApplicationForItem, LSGetApplicationForURL, LSGetApplicationForInfo), or that determine whether a given application can open a designated item (LSCanRefAcceptItem, LSCanURLAcceptURL), to specify the application’s desired role or roles with respect to the item. For example, to request only an editor application, specify kLSRolesEditor; if either an editor or a viewer application is acceptable, specify kLSRolesEditor | kLSRolesViewer.
