The two functions in openCV cvLoadImage and cvSaveImage accept file path's as arguments.

For example, when saving a image it's cvSaveImage("/tmp/output.jpg", dstIpl) and it writes on the disk.

Is there any way to feed this a buffer already in memory? So instead of a disk write, the output image will be in memory.

I would also like to know this for both cvSaveImage and cvLoadImage (read and write to memory buffers). Thanks!

My goal is to store the Encoded (jpeg) version of the file in Memory. Same goes to cvLoadImage, I want to load a jpeg that's in memory in to the IplImage format.
