4.3.28 is_FreeImageMem
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
Points to the starting address of the memory (e.g. set in the
is_AllocImageMem() function)
Return values
The image memory is already included in the sequence
and cannot be added again.
The driver could not release the allocated memory.
IS_CANT_COMMUNICATE_WITH_DRIVER
Communication with the driver failed because no driver
has been loaded.
An attempt to initialize or select the camera failed (no
camera connected or initialization error).
IS_INVALID_MEMORY_POINTER
Invalid pointer or invalid memory ID
One of the submitted parameters is outside the valid
range or is not supported for this sensor or is not
available in this mode.
An IO request from the uc480 driver failed. Possibly the
versions of the uc480_api.dll (API) and the driver file
(uc480_usb.sys) do not match.
