        HIGMULT hMult,
        LPAT_UINT lpNumFrames,
        LPAT_UINT lpDuration
);

Example:

 
Copy Code 
AT_ERRCOUNT nErrcount;  /* Number of errors on stack */
HIGMULT hMult;          /* Multimedia instance handle */
AT_UINT numFrames;      /* Total number of frames in file */

nErrcount = IG_mult_duration_get(hMult, &numFrames, &msDuration);
