Libbpf userspace function bpf_raw_tracepoint_open

0.0.1

Low level wrapper around the BPF_RAW_TRACEPOINT_OPEN syscall command.

Definition

int bpf_raw_tracepoint_open(const char *name, int prog_fd);

Parameters

  • name: name of the raw tracepoint
  • prog_fd: BPF program file descriptor

Return

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

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.
