Libbpf userspace function bpf_raw_tracepoint_open
Low level wrapper around the BPF_RAW_TRACEPOINT_OPEN
syscall command.

int bpf_raw_tracepoint_open(const char *name, int prog_fd);
Parameters
name
: name of the raw tracepointprog_fd
: BPF program file descriptor
Return

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

function should be used instead.
