- For my solution I decided to read…and store JPEG file information…into a structure called, Images.…If the system hasn't defined a maximum…length for the path or filename,…the header file sets constants for both…PATH_MAX and NAME_MAX.…The BUFFSIZE constant,…represents the maximum string length…for an image caption.…Which can be up to 2,000 characters.…Also, note the UNIX definition.…If you're compiling under Windows,…change the definition to MSDOS,…and save that before compiling.…
To store the image structures,…I use the second and most terrifying…C Language construct after an array of pointers,…the Linked List.…The structure for that list is defined…in the header file as Images.…It stores the image name, filename extension,…caption, directory, and of course, a link…to the next item in the list.…The source code for PicNsort C…is divided into three parts.…The first part is handled in the main…function, which includes checking…for command line arguments.…
The second part is handled by the…finddir function, which recursively…
Dan introduces challenges and then provides an overview of his solutions in C. Challenges include topics such as statistical analysis, searching directories for images, and accessing peripheral devices.
