The final solution to the final exercise! These last few exercise solutions are not ideal by any measure of coding excellence, but they function. I plan to come back to this some day, with better debugging knowledge. Then I can correct any issues. Solve Exercise 8-7: malloc & free, improved 2022-01-24T05:20:25Z zlg zlg@zlg.space 2022-01-24T05:20:25Z urn:sha1:06988a01833c5f669f83b16b35f0b3f70c36f807 There wasn't much to check for, but I checked for what I could think of. Solve Exercise 8-6: calloc() 2022-01-24T01:59:56Z zlg zlg@zlg.space 2022-01-24T01:59:56Z urn:sha1:2bbb384783f667226e117e62992779498bc7e5b8 I chose to implement calloc() by calling malloc. This exercise went well, but I found it difficult to verify the contents of the headers and buffers within memory. Valgrind showed the correct number of bytes allocated, and a memory dump pointed to a good result, but research was not conclusive. Solve Exercise 8-05: fsize extended 2022-01-19T05:58:37Z zlg zlg@zlg.space 2022-01-19T05:58:37Z urn:sha1:b1805ae57e314be9d56c099a282206053043fa4b This exercise uses the standard library instead of the homegrown dirent.h outlined in the book. This is due to misbehavior in outputting the file or directory names. This pointed to a data mismatch between the data model supplied by the book and the data model actually used by my operating system (GNU/Linux).
