Enum LinuxProcessMemoryReader 

pub enum LinuxProcessMemoryReader {
    Fast {
        pid: Pid,
    },
    Slow {
        file: File,
    },
}

The memory reader for the process This concrete type is used for easier generic trait implementation in the coredump module.

Variants

Fast

A fast process memory reader employing the process_vm_readv system call available on Linux 3.2+. It might be disabled on some systems in the kernel configuration.

Fields

pid: Pid

The process ID of the target process

Slow

A slow but more compatible process memory reader, uses the /proc/<pid>/mem file.

Fields

file: File

The file handle to the /proc/<pid>/mem file

Implementations

impl LinuxProcessMemoryReader

pub fn new(pid: Pid) -> Result<Self, CoreError>

Create a new process memory reader for the given process ID. It will use the fast method if available, otherwise it will fall back to the slow method.

Trait Implementations

impl ReadProcessMemory for LinuxProcessMemoryReader

fn read_process_memory( &mut self, base: usize, buf: &mut [u8], ) -> Result<usize, CoreError>

Read process memory into buf starting at the virtual address base, and returns the number of bytes and or the error.
