SDL_PeepEvents

Use this function to check the event queue for messages and optionally return them.

Syntax

int SDL_PeepEvents(SDL_Event*      events,
                   int             numevents,
                   SDL_eventaction action,
                   Uint32          minType,
                   Uint32          maxType)

Function Parameters

events

destination buffer for the retrieved events

numevents

if action is SDL_ADDEVENT, the number of events to add back to the event queue; if action is SDL_PEEKEVENT or SDL_GETEVENT, the maximum number of events to retrieve

action

action to take; see Remarks for details

minType

minimum value of the event type to be considered; SDL_FIRSTEVENT is a safe choice

maxType

maximum value of the event type to be considered; SDL_LASTEVENT is a safe choice

Return Value

Returns the number of events actually stored or a negative error code on failure; call SDL_GetError() for more information.

Code Examples

Add a code example here.

Remarks

action may be any of the following:

SDL_ADDEVENT

up to numevents events will be added to the back of the event queue

SDL_PEEKEVENT

up to numevents events at the front of the event queue, within the specified minimum and maximum type, will be returned and will not be removed from the queue

SDL_GETEVENT

up to numevents events at the front of the event queue, within the specified minimum and maximum type, will be returned and will be removed from the queue

{i} This function is thread-safe.

You may have to call SDL_PumpEvents() before calling this function. Otherwise, the events may not be ready to be filtered when you call SDL_PeepEvents().
