IltmmPlay::CheckSeekingCapabilities

#include "ltmm.h"

C Syntax	HRESULT IltmmPlay_CheckSeekingCapabilities(pPlay, Mask, pCaps)
C++ Syntax	HRESULT CheckSeekingCapabilities(Mask, pCaps)

IltmmPlay *pPlay;	/* pointer to an interface */
long *Mask;	/* pointer to a variable */
long *pCaps;	/* pointer to a variable */

Queries whether the object is capable of performing a specified seeking operation.

Parameter	Description
pPlay	Pointer to an IltmmPlay interface.
Mask	Pointer to a bitwise combination of one or more ltmmPlay_Seek attributes. When the function returns, the value indicates which of those attributes are available.
pCaps	Pointer to a variable that receives the queried capabilities.

Returns

S_OK	The function was successful.
<> S_OK	An error occurred. Refer to the Error Codes or the HRESULT error codes in the DirectShow documentation.

Comments

Declare a long value equal to the bitwise-OR combination of the ltmmPlay_Seek attributes that you want to test. Pass this value in the Mask parameter. When the function returns, pCaps contains a subset of the original bits, indicating which capabilities are present. The return value indicates whether some, none, or all of the requested capabilities are present.
