This chapter provides information about the interface to ESROS services. It is intended for the users of the ESROS sublayer.
The ESROS API is available in two different styles. In the first case the events are made available to the user of the API through function calls. This is known as the Function Call API. Functions of this API implementation all have the ESRO_ prefix. In the second case ESROS events trigger call backs to functions registered by the user of the ESROS API. This is known as Call back API. Functions of this API implementation all have the ESRO_CB_ prefix, in which CB stands for Call Back.
