IMAQ image locking

[dennex]

Hi,

I'm using C++ dll to do operations on IMAQ image buffer in the way shown in this link

My question is about image buffer locking mecanism. How do we ensure that the image buffer will not be used by another process while it is used in the DLL call?

Hi dennex,

Unfortunately there is no public API function currently available in LV or C to lock images for external use. You currently have to manually synchronize your DLL calls with other functions (both yours and Vision's) that might modify the image.
