Module redbpf_probes::uprobe

User-space probes.

UProbes are hooks on the entry (uprobe) or exit (uretprobe) of user-space functions. For an overview of UProbes and how they work, see https://www.kernel.org/doc/Documentation/trace/uprobetracer.txt.

Example

Do something when the OpenSSL SSL_write function is called:

use redbpf_probes::uprobe::prelude::*;

#[uprobe]
fn SSL_write(regs: Registers) {
    let buf = regs.parm2() as *const c_void;
    let num = regs.parm3() as i32;
    // do something with the buffer
    // ...
}
