   3 NAME
   4      Pread, Pread_string - read data from a process

  12          uintptr_t address);

  16          uintptr_t address);
  17 
  18 DESCRIPTION
  19      The Pread() function reads data from the process handle P starting at
  20      address in the address space of the process and reads at most nbytes of
  21      data into buf and is logically analogous to the pread(2) function.
  22 
  23      For live processes, this function is equivalent to reading from the /proc
  24      file system as file for the process.  For core files and file handles, it
  25      reads and writes from the logical address space and not the corresponding
  26      offset of the file itself.  For example, a core file contains a sparse
  27      representation of the address space of a crashed process and unmapped
