Detailed Description

The PPB_Core interface contains pointers to functions related to memory management, time, and threads on the browser.


Field Documentation

AddRefResource() adds a reference to a resource.

Parameters:
[in]configA PP_Resource corresponding to a resource.
void(* PPB_Core::CallOnMainThread)(int32_t delay_in_milliseconds, struct PP_CompletionCallback callback, int32_t result)

CallOnMainThread() schedules work to be executed on the main module thread after the specified delay.

The delay may be 0 to specify a call back as soon as possible.

The result parameter will just be passed as the second argument to the callback. Many applications won't need this, but it allows a module to emulate calls of some callbacks which do use this value.

Note: CallOnMainThread, even when used from the main thread with a delay of 0 milliseconds, will never directly invoke the callback. Even in this case, the callback will be scheduled asynchronously.

Note: If the browser is shutting down or if the module has no instances, then the callback function may not be called.

Parameters:
[in]delay_in_millisecondsAn int32_t delay in milliseconds.
[in]callbackA PP_CompletionCallback callback function that the browser will call after the specified delay.
[in]resultAn int32_t that the browser will pass to the given PP_CompletionCallback.

GetTime() returns the "wall clock time" according to the browser.

Returns:
A PP_Time containing the "wall clock time" according to the browser.

GetTimeTicks() returns the "tick time" according to the browser.

This clock is used by the browser when passing some event times to the module (e.g. using the PP_InputEvent::time_stamp_seconds field). It is not correlated to any actual wall clock time (like GetTime()). Because of this, it will not run change if the user changes their computer clock.

Returns:
A PP_TimeTicks containing the "tick time" according to the browser.

IsMainThread() returns true if the current thread is the main pepper thread.

This function is useful for implementing sanity checks, and deciding if dispatching using CallOnMainThread() is required.

Returns:
A PP_Bool containing PP_TRUE if the current thread is the main pepper thread, otherwise PP_FALSE.

ReleaseResource() removes a reference from a resource.

Parameters:
[in]configA PP_Resource corresponding to a resource.
