Asynchronous function: A function that returns immediately to the application and returns event notification at some future time. EV_ASYNC is specified in the function's mode argument. This allows the current thread of code to continue while the function is running.
Backup handlers: Handlers that are enabled for all events on one device or all events on all devices.
Device: Any object, for example, a board or a channel, that can be manipulated through a physical library.
Device handle: Numerical reference to a device, obtained when a device is opened using an xx_open( ) function, where xx is the prefix defining the device to be opened. The device handle is used for all operations on that device.
Device name: Literal reference to a device, used to gain access to the device through an xx_open( ) function, where xx is the prefix defining the device type to be opened.
Dialogic Standard Runtime Library (SRL): Device-independent library that consists of event management functions and standard attribute functions.
Event: Any message sent from the device.
Handler: A user-defined function called by the SRL when a specified event occurs on a specified event.
Event management functions: SRL functions that connect and disconnect events to application-specified event handlers, allowing the user to retrieve and handle events when they occur on a device.
Solicited event: An expected event. It is specified using one of the device library's asynchronous functions. For example, for dx_play( ), the solicited event is "play complete."
Standard attribute functions: SRL functions that return general information about the device specified in the function call. Standard attribute information is applicable to all Dialogic devices that are supported by the SRL.
Subdevices: Any device that is a direct child of another device, for example, a channel is a subdevice of a board device. Because "subdevice" describes a relationship between devices, a subdevice can be a device that is a direct child of another subdevice.
Synchronous function: A function that blocks the application until the function completes. EV_SYNC is specified in the function's mode argument.
Unsolicited event: An event that occurs without prompting, such as a silence-on or silence-off event on a channel.
