4.3.66 is_LockSeqBuf
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.
Input parameters
Number of the image memory to be locked (1…max) or
IS_IGNORE_PARAMETER: The image memory will be identified by its starting
address only.
Starting address of the image memory to be locked
Attention
nNum indicates the location in the sequence list, not the memory ID assigned using is_AllocImageMem() .
Return values
An internal structure has an incorrect size.
One of the submitted parameters is outside the valid
range or is not supported for this sensor or is not
available in this mode.
