ProviderGetLocation (Windows Embedded CE 6.0)

1/6/2010

A Provider DLL implements this function. The Location Framework calls this export when it needs reports that this Provider can generate.

Syntax

DWORD  ProviderGetLocation(
   PROVIDER_CONTROL_BLOCK* pProvControlBlock
);

Parameters

  • pProvControlBlock
    Pointer to a PROVIDER_CONTROL_BLOCK, which contains information about the current request for the device’s position.

Return Value

If the Provider returns any value other than ERROR_SUCCESS, the Location Framework will assume that a fatal error has occurred and will cause the plugin to go into the PLUGIN_STATE_ERROR state. If a Provider returns before it has been requested to via a ProviderStop, the Location Framework will treat this as an illegal operation and put the plugin into the PLUGIN_STATE_ERROR state.

Remarks

ProviderGetLocation is called whenever the Location Framework determines that a report that this Provider can generate is required. This can be the result of an application requiring the report directly or alternately a Resolver needing the report to resolve into another type. The Provider is abstracted from the final use of its report and should generate reports as always based on this configuration.
