how ho hook engine function

[cspp]

Lets say I need to hook g_pEngine->pfnPlaySound

g_pEngine->pfnPlaySound = myfunc ( do I need to pass cl_enginefunc_s struct to it or not? )
because return g_pEngine->pfnPlaySound(soound,vol,pitch ) leed to crash . I suppose myfunc shoud be structure* void.
Can someone explain how to do it properly

Let me see your code.

[cspp]

void HookFunction(){

	

	g_pClient->HUD_Redraw = HUD_Redraw;
	g_pClient->HUD_Frame = HUD_Frame;	
	
	
	
	g_pEngine->pfnPlaySound = plays;  //here





and

void [or what??] plays(const char *sound,float vol, float pitch)
{
	
	ConsolePrintColor(22, 222, 22, "hook sound %s \n",sound);

	return g_pEngine->pfnPlaySound(sound, vol, pitch);   //wrong 
}

- - - Updated - - -

I found return g_Engine.pfnPlaySound(sound, vol, pitch); is correct

I have another question

if I hook simple command like disconnect

pcmd_t hookdisc;

hookdisc = CommandByName("disconnect");	
hookdisc->function = (xcommand_t)mydisconnect;


void mydisconnect()
{



how to return original function ? because if I do engine-> clientcmd disconenct  it will be infinite loop

First of all, you can't return a void.

Are you sure that your sound parameters are correct?.

int plays(const char *sound,float vol, float pitch)
{
	if(g_pEngine)
           ConsolePrintColor(22, 222, 22, "Engine Found \n",sound);

	return g_pEngine->pfnPlaySound(sound, vol, pitch);   //wrong 
}

[cspp]

yes because original func (pfnPlaySound) is void.
so

void plays(const char *sound,float vol, float pitch)
{
	if(!blockplaysound)
	return g_Engine.pfnPlaySound(sound, vol, pitch);
}

works well.
