Hi, In Solairs Dtrace User Guide, page 193, it lists the arguments of ERROR probe. One of these arguments is arg3, it is explained as "The DIF offset into that action or -1 if not applicable". Then what does the abbr. DIF mean? Regards TJ
DIF = D Intermediate Format See page 4, DIF: http://www.sun.com/bigadmin/content/dtrace/dtrace_usenix.pdf "... DIF, is a small RISC instruction set designed for simple emulation and on-the-fly code generation." Rayson On 3/8/07, ??
