| Copy Code |
|
|---|---|
AT_ERRCOUNT nErrcount; /* Number of errors on stack */ HIGMULT hMult; /* Multimedia instance handle */ AT_UINT numFrames; /* Total number of frames in file */ AT_UINT msDuration; /* Duration of file in milliseconds */ nErrcount = IG_mult_duration_get(hMult, &numFrames, &msDuration); |

Remarks:
You can pass NULL for one of these arguments if you only need the other one. You can use this function to determine how many frames are in a multimedia instance and how long it would play for if played at normal speed.
