Synopsis of uprobe_tracer
-------------------------
- p[:[GRP/]EVENT] PATH:SYMBOL[+offs] [FETCHARGS] : Set a uprobe
- r[:[GRP/]EVENT] PATH:SYMBOL[+offs] [FETCHARGS] : Set a return uprobe (uretprobe)
- -:[GRP/]EVENT : Clear uprobe or uretprobe event
+ p[:[GRP/]EVENT] PATH:OFFSET [FETCHARGS] : Set a uprobe
+ r[:[GRP/]EVENT] PATH:OFFSET [FETCHARGS] : Set a return uprobe (uretprobe)
+ -:[GRP/]EVENT : Clear uprobe or uretprobe event
GRP : Group name. If omitted, "uprobes" is the default value.
EVENT : Event name. If omitted, the event name is generated based
- on SYMBOL+offs.
+ on PATH+OFFSET.
PATH : Path to an executable or a library.
- SYMBOL[+offs] : Symbol+offset where the probe is inserted.
+ OFFSET : Offset where the probe is inserted.
FETCHARGS : Arguments. Each probe can have up to 128 args.
%REG : Fetch register REG
