geoOpen()
The function opens a geo source.
Synopsis
int geoOpen(string source = "");
Parameters
| Parameter | Description |
|---|---|
| source | Name of the geosource. |
Return value
Returns 0 when a source could be opened, else -1
Description
If given an empty string or no argument, it opens a position source that reads from the system's default sources of location data, or the plugin with the highest available priority. If a source name is given, that source will be opened (it will be one of geoSources()). An opened source will start to request updates.
Only one source can be open at any given time.
The function will use location tracking. The time required to open a geo source and get the update of the current position does depend on the device connection to a satellite in case the satellite-based positioning method is used (GPS or GLONASS) or on the device internet connection in case the non-satellite based positioning method is used (3GPP cell identifier or WiFi based positioning).
