Syntax
INT is_FreeImageMem (HIDS hCam, char* pcImgMem, INT id)
Description
is_FreeImageMem() releases an image memory that was allocated using is_AllocImageMem() and
removes it from the driver management.
Note
If the memory was not allocated using an SDK function, you need to call is_FreeImageMem() as
well. Otherwise, there may be errors when the driver keeps trying to access this memory.
This does however not release the memory. So you need to make sure that the memory will be
released again.
Input parameters
