Libbpf userspace function `bpf_raw_tracepoint_open_opts`

1.4.0

Low level wrapper around the BPF_RAW_TRACEPOINT_OPEN syscall command.

Definition

int bpf_raw_tracepoint_open_opts(int prog_fd, struct bpf_raw_tp_opts *opts);

Parameters

prog_fd: BPF program file descriptor
opts: options for configuring the raw tracepoint

Return

>0, file descriptor of the raw tracepoint; negative error code, otherwise

`struct bpf_raw_tp_opts`

struct bpf_raw_tp_opts {
    size_t sz; /* size of this struct for forward/backward compatibility */
    const char *tp_name;
    __u64 cookie;
    size_t :0;
};

Usage

This function should only be used if you need precise control over the raw tracepoint opening process. In most cases the bpf_program__attach_raw_tracepoint or bpf_program__attach_raw_tracepoint_opts function should be used instead.

Example
