Function Documentation

◆ DetectDirectX()

void DetectDirectX	(	unsigned int *	p_version,
		BOOL *	p_found
	)

[AI] Detects the version of DirectX installed and indicates if it is present.

Parameters

p_version	[OUT] Receives the version number in hexadecimal (e.g., 0x100, 0x200, 0x300, 0x500). [AI]
p_found	[OUT] Will be set to TRUE or platform indicator if DirectX-related components are found. [AI]

[AI] Examines the Windows platform and attempts to load key DirectX components (DirectDraw and DirectInput) to determine the DirectX version installed. This includes probing the system for the presence of the required DLLs and interfaces, and incrementally setting the version according to available interfaces and features (DirectDraw2, DirectInput, DirectDrawSurface3, etc.). Sets both the version and a found/platform marker.

◆ DetectDirectX5()

BOOL DetectDirectX5 ( )

[AI] Checks whether DirectX 5 or a later version is present and available on the system.

[AI] This function calls DetectDirectX to determine the installed DirectX version and whether DirectX is found, then returns TRUE if the version is 5.0 (0x500) or newer.

Returns: TRUE if DirectX 5.0 or newer is detected, otherwise FALSE. [AI]
