is_GetActSeqBuf
Syntax
INT is_GetActSeqBuf (HIDS hCam, INT* pnNum,
char** ppcMem, char** ppcMemLast);
Description
Using is_GetActSeqBuf(), you can determine the image memory which is currently used for
capturing an image (ppcMem) or the image memory that was last used for capturing an image (
ppcMemLast). This function is only available if you have enabled ring buffering.
This number is not the ID of the image memory that was allocated using the is_AllocImageMem
() function, but the running number from the order in which memory was allocated by the
is_AddToSequence() function.
Input Parameters
Contains the number of the image memory currently used for image capturing.
If image capturing is already in progress when is_GetActSeqBuf() is called,
pnNum will return the value 0 until the sequence arrives at the first image
memory again.
Contains the starting address of the image memory currently used for image
capturing.
Contains the starting address of the image memory last used for image
capturing.
Return Values
Function executed successfully
