I have been writing and maintaining AUL/MyDUL software for three years. Just wondering how much lines of C code I have wrote and did a count, strangely there are less lines than I have expected (10000 lines).
Oracle DMP file format interface.
C:\mydul-b5>wc -l dmpfile.*
245 dmpfile.c
41 dmpfile.h
286 total
Oracle data block format interface.
C:\mydul-b5>wc -l block.*
5795 block.c
438 block.h
6233 total
AUL/MyDUL command tools interface.
C:\mydul-b5>wc -l mydul.*
3443 mydul.c
105 mydul.h
3548 total
So for a software tools, 10 lines every day by average is enough. I did not believe it few years ago, always thinking that I can write few hundreds or thousands of lines per day.
