Initializing a buffer in call library function for capturing image data

[kamalm2]

Hi all,
How can I initializing a buffer in call library function for capturing image data from a camera?




Thanks

If you want your DLL code to initialize buffer to pass data back to LabVIEW, then you have to use LabVIEW's memory manager functions e.g. DSSetHandleSize etc..

Here is your starting point

Hi Kamal,
An easy way could be to use, e.g., the "Initialize Array.vi" from the Array palette or any other LabView code to generate an array of the desired type, dimension and size. Then configure the Call Library Node to pass a pointer to the array to your external code.

Best regards
