If it DOES, then you can sort it directly.
No, it does not. The reason that it _seems_ to be working in both cases is due to the fact that you are probably allocating the memory sequentially, and not adding or removing elements from the list before you try and sort it. Let me assure you that calling qsort on a linked list is undefined behavior. Yes it may work for you now, but next week it may not.. You can't tell because it's not defined behavior. Using an array (either directly, or through a wrapper function) does have a defined behavior and will work every time (assuming there are no hardware problems, etc) regardless of the phases of the moon, or anything else. So if you like random crashing, data munging, and other fun debugging headaches, feel free to continue as is. If you want consistancy, and error free code, use an array when calling qsort. ~Kender ===== -----BEGIN GEEK CODE BLOCK----- Version 3.1 GCS/L/C/O d-(+) s++: a-- C+++$>++++ UBLS++++$ P+++(--)$ L+++>++++ E--- W+>++$ N !o K? w(--) !O M- !V PS+ PE(++) Y+ PGP->+ t+ 5 X+() R(+) tv+@ b++(+++) !DI+++ D G(-) e>+++$ h---() r+++ y+++ ------END GEEK CODE BLOCK------ __________________________________ Do you Yahoo!?
