      PerfEventOpen:
      @options: key-value pair of attributes for the perf_event_open() syscall.
      @pid: the process id to monitor, or -1 for system-wide.
      @cpu: affinity to cpu.
      @group: a FD handle for an existing group
      @flags: flags for perf_event_open() syscall.
      @perf_stream_fd: (out): A fd to communicate with perf.

      Performs the perf_event_open() syscall with elevated privileges and passes
      the resulting fd back to the calling process.

      GetProcFile:
      @path: the path including "/proc/" prefix.

      Gets a file from /proc/ or /sys/.

      The file must be a C-string (no embedded NUL bytes) but need not be UTF-8.

      Returns: an array of bytes.

      Since: 3.34

    <!--
      GetProcFd:
      @path: the path within /proc or /sys

      Like GetProcFile, but returns a FD for the file.

      This is useful for situations where you need to seek() back to 0 to
      optimize the parsing of the file contents.

      Returns: a file-descriptor
