I want to read an image(JPEG) file from hard disk to memor开发者_开发知识库y. How can I do this? What kind of variable type should I use ?

Use a big char array

char data[4096]

And fread(3) chunks into it. Of course an entire JPEG won't fit in 4096 bytes, but perhaps you can work with chunks instead of the entire file ?
