/* Replacements for malloc and strdup with error checking. Too trivial
|
|
to be worth copyrighting :-). I did that because a lot of code used
|
|
malloc and strdup without checking for NULL pointer, and I like some
|
|
message better than a core dump... --marekm
|
|
|
|
Yeh, but. Remember that bailing out might leave the system in some
|
|
bizarre state. You really want to put in error checking, then add
|
|
some back-out failure recovery code. -- jfh */
