Provides the core foundation to initialize and access the Steamworks API.

All of the types listed here are global defines and not associated with any one specific API.

Functions

These are global functions which do not require an interface to set up. You can read more about these functions in the Steamworks API Overview.

SteamAPI_Init

Initializes the Steamworks API.

See Initialization and Shutdown for additional information.

Returns: bool
true indicates that all required interfaces have been acquired and are accessible.
false indicates one of the following conditions:

• The Steam client isn't running. A running Steam client is required to provide implementations of the various Steamworks interfaces.
  
• Steam-klienten kunne ikke avgjøre app-ID-en til spillet. Hvis du kjører applikasjonen din direkte fra en kjørbar fil eller et feilsøkingsprogram, så må steam_appid.txt finnes i spillets mappe ved siden av den kjørbare filen, og denne må inneholde app-ID-en din og ingenting annet. Steam leter etter denne filen i gjeldende mappe. Hvis du kjører den kjørbare filen fra en annen mappe, så må du muligens flytte steam_appid.txt.
  
• Applikasjonen kjører ikke under samme kontekst i operativsystemet som Steam-klienten, som under en annen bruker eller uten administratortilgang.
  
• Pass på at du eier en lisens for app-ID-en eller den aktive Steam-kontoen. Spillet må dukke opp i Steam-biblioteket ditt.
  
• App-ID-en din er ikke fullstendig satt opp, f.eks. i Utgivelsestilstand: Utilgjengelig eller så mangler standardpakker.

Example:

SteamAPI_ReleaseCurrentThreadMemory

Frigjør internt minne i Steamworks-API-et som er tilknyttet kalling av tråden.

De fleste funksjoner i Steamworks-API-et tilordner litt lokalt minne i tråden for lagring av parametre – å kalle dette frigjør slikt minne manuelt. Denne funksjonen kalles automatisk av SteamAPI_RunCallbacks. Et program som kun får tilgang til Steamworks-API-et fra en enkelt tråd trenger derfor aldri å eksplisitt kalle denne funksjonen.

SteamAPI_RestartAppIfNecessary

Navn	Type	Beskrivelse
unOwnAppID	uint32	App-ID-en til dette spillet.

Sjekker om den kjørbare filen din ble startet gjennom Steam, og starter den på nytt gjennom Steam hvis dette ikke er tilfellet.

Se Initialization and Shutdown for ytterligere informasjon.

Resultat: bool
Hvis dette gir true så startes Steam-klienten hvis nødvendig, og så startes spillet gjennom denne, og du bør da avslutte prosessen så snart som mulig. Dette kjører i prinsippet steam://run<AppId>, så det er ikke sikkert at nøyaktig den samme kjørbare filen startes på nytt, ettersom det alltid starter på nytt fra versjonen som er installert i bibliotekmappen til Steam.

Hvis det gir false så ble spillet startet gjennom Steam-klienten, og ingen handling kreves. Et unntak er at hvis en fil med navn steam_appid.txt, så returnerer dette alltid false. Dette lar deg utvikle og teste uten å starte spillet gjennom Steam-klienten. Husk på å fjerne filen steam_appid.txt når du laster opp spillet til depotet ditt på Steam!

Eksempel:

SteamAPI_RunCallbacks

Sender ut tilbakekall og resultater til alle registrerte lyttere.

Det beste er å kalle dette med en frekvens på >10 Hz – jo mer tid mellom kall, jo mer potensiell forsinkelse er det mellom når man mottar hendelser eller resultater fra Steamworks-API-et. De fleste spill kaller dette en gang per gjengivelsesramme. All registered listener functions will be invoked during this call, in the callers thread context.

SteamAPI_RunCallbacks is safe to call from multiple threads simultaneously, but if you choose to do this, callback code could be executed on any thread. Et alternativ er å kalle SteamAPI_RunCallbacks kun fra hovedtråden, og så kalle SteamAPI_ReleaseCurrentThreadMemory regelmessig på andre tråder.

SteamAPI_SetMiniDumpComment

Navn	Type	Description
pchMsg	const char *	The message to attach to the minidump. This must be null terminated.

Attaches an arbitrary comment to embed in the minidump.

Some examples that you may want to include are what level the user was playing, how many players on the server, how much memory is free, etc.
This must be called before calling SteamAPI_WriteMiniDump.

SteamAPI_Shutdown

Lukker Steamworks-API-et og frigir pekere og minne.

Du bør kalle dette når prosessen lukkes hvis mulig.

Dette løser ikke Steam Overlay fra spillet ettersom det ikke finnes noen garanti for at gjengivelses-API-et er ferdig med å bruke det.

SteamAPI_WriteMiniDump

Name	Type	Description
uStructuredExceptionCode	uint32	The structured exception code.
pvExceptionInfo	void*	The EXCEPTION_POINTERS containing the actual exception information.
uBuildID	uint32	A Build ID to track what version of the app submitted this minidump. This is not the same as a Steam build ID and is used only for crash reporting.

Writes and uploads a minidump to report crashes.

See Steam Error Reporting for more information.

You can add an optional comment by calling SteamAPI_SetMiniDumpComment before you call this function.
