[Libexif-devel] Question about JPG file access and Exif Header access

[Benny S. <ich...@pa...>]

I am trying to use libexif for the first time.

I am working in an embedded environment and I want to read from and write to
Exif headers in JPG files stored on a compact flash card.

I have not done any of this before.

I have looked at the test programs (test-mem.c , test-value.c, etc.)
included with the libexif package.

I do not see any file access commands in these programs, wherein a JPG file
is opened or closed.

Also, I am trying to understand how libexif will know about and be able to
write to/read from the memory on my microcontroller module ((I have 128K of
RAM available).

I would appreciate any help you can give me.
