Cause of Wild Pointers
Wild pointers are created by omitting necessary initialization prior to first use. Thus, strictly speaking, every pointer in programming languages which do not enforce initialization begins as a wild pointer.
This most often occurs due to jumping over the initialization, not by omitting it. Most compilers are able to warn about this.
int f(int i) { char *dp; /* dp is a wild pointer */ static char *scp; /* scp is not a wild pointer: * static variables are initialized to 0 * at start and retain their values from * the last call afterwards. * Using this feature may be considered bad * style if not commented */ }Read more about this topic: Dangling Pointer
Famous quotes containing the word wild:
“Reason sits firm and holds the reins, and she will not let the feelings burst away and hurry her to wild chasms. The passions may rage furiously, like true heathens, as they are; and the desires may imagine all sorts of vain things: but judgement shall still have the last word in every argument, and the casting vote in every decision.”
—Charlotte Brontë (1816–1855)
