; Function:   _MemoryOpen($iv_Pid[, $iv_DesiredAccess[, $iv_InheritHandle]])
; Description:    Opens a process and enables all possible access rights to the
;               process.  The Process ID of the process is used to specify which
;               process to open.  You must call this function before calling
;               _MemoryClose(), _MemoryRead(), or _MemoryWrite().
; Parameter(s):  $iv_Pid - The Process ID of the program you want to open.
;               $iv_DesiredAccess - (optional) Set to 0x1F0FFF by default, which
;                              enables all possible access rights to the
;                              process specified by the Process ID.
;               $iv_InheritHandle - (optional) If this value is TRUE, all processes
;                              created by this process will inherit the access
;                              handle.  Set to 1 (TRUE) by default.  Set to 0
;                              if you want it FALSE.
; Requirement(s):   None.
; Return Value(s):  On Success - Returns an array containing the Dll handle and an
;                         open handle to the specified process.
;               On Failure - Returns 0
;               @Error - 0 = No error.
;                      1 = Invalid $iv_Pid.
