I think you should compute and sum the sizes of the tar files
themselves. Suppose you readdir(), make a list of files that look
relevant, and stat() each one. total_size is the sum of the file
sizes. Then you work your way through the list of files and read each
one. done_size is the total size of all files you've read completely
plus the number of bytes you've read from the current file so far.
