Are Imaq C Vision Functions reentrant?

[satriani81]

Hi all,
I have to build a multi-camera parallel acquisition and analysis software so multiple threads are required. I decided to write a C dll containing vision code with imaq functions (I don't want to use activeX because marshalling slowes a lot the execution -see here for more information-), and I call this dll's functions from VB. In VB I create various threads from wich I call vision code in dll. My C code in dll is reentrant, but are C Imaq functions safe thread and reentrant  ?
Thanks for you care!

HI,

Here is a document that discusses multi-threading in IMAQ:
