Syntax
INT is_LockSeqBuf (HIDS hCam, INT nNum, char* pcMem)
Description
is_LockSeqBuf() locks write access to an image memory within a sequence. In the capturing process, locked
image memories will be skipped in the sequence list of image memories to be used. This way, you can avoid that
image data which are required for further processing will be overwritten by newly captured data. Full access to the
image memory is still guaranteed. You can lock any number of image memories at the same time.
Using the is_UnlockSeqBuf() function, you can re-enable write access to the image memory.

hCam

nNum
Number of the image memory to be locked (1…max) or
IS_IGNORE_PARAMETER: The image memory will be identified by its starting
