Function nix::sys::uio::process_vm_writev
pub fn process_vm_writev(pid: crate::unistd::Pid, local_iov: &[IoVec<&[u8]>], remote_iov: &[RemoteIoVec]) -> Result<usize>The portability is definied by:
#[cfg(target_os = "linux")]Documentation
Write data directly to another process’s virtual memory
(see process_vm_writev(2)).
local_iov is a list of IoVecs containing the data to be written,
and remote_iov is a list of RemoteIoVecs identifying where the
data should be written in the target process. On success, returns the
number of bytes written, which will always be a whole
number of remote_iov chunks.
This requires the same permissions as debugging the process using
ptrace: you must either be a privileged process (with
CAP_SYS_PTRACE), or you must be running as the same user as the
target process and the OS must have unprivileged debugging enabled.
This function is only available on Linux.
