dwatch allows you to customnize the predicate (condition) for when information is displayed. The DTrace syntax for this is: probe[, ...] /predicate/ { [actions] } But if predicate is something like "*args[1]!=NULL" to test that the first pointer in an array is non-NULL, the syntax produced is: probe[, ...] /*arg1!=NULL/ { [actions] } The issue being that "/*" is the beginning of a comment and thus the following error is emitted: dtrace: failed to compile script /dev/stdin: line 535: /* encountered inside a comment This patch adds whitespace around the argument given to -t, producing: probe[, ...] / *arg1!=NULL / { [actions] } Sponsored by: Smule, Inc. |
