Functions

func AttachUretprobe

func AttachUretprobe(attachSymbol string, prog *ebpf.Program, ex *link.Executable, opts *link.UprobeOptions) (link.Link, error)

AttachUretprobe attaches a uretprobe to the function at attachPath and attachSymbol. The probe will be attached to all return instructions in the function.

attachPath is the path to the ELF file containing the function. attachSymbol is the name of the function to attach the probe to. prog is the eBPF program to attach. ex is the executable to attach the probe to. opts are the options for the probe.

Types

type Function

type Function struct {
	Offset  uint64
	Size    uint64
	Prog    *elf.Prog
	Returns []uint64
}

Function represents a function in an ELF file.
