H A Dtracepoints.rst16 A tracepoint placed in code provides a hook to call a function (probe)
17 that you can provide at runtime. A tracepoint can be "on" (a probe is
18 connected to it) or "off" (no probe is attached). When a tracepoint is
22 and adds a data structure in a separate section). When a tracepoint
23 is "on", the function you provide is called each time the tracepoint

30 which prototypes are described in a tracepoint declaration placed in a
40 - A tracepoint definition, placed in a header file.
41 - The tracepoint statement, in C code.
43 In order to use tracepoints, you should include linux/tracepoint.h.
