; 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.
; $if_InheritHandle - (optional) If this value is TRUE, all processes created by
; this process will inherit the access handle. Set to TRUE
; (1) by default. Set to 0 if you want it to be FALSE.
; Requirement(s): A valid process ID.
; 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.
; 2 = Failed to open Kernel32.dll.
; 3 = Failed to open the specified process.

; 'dword'(32bit(4byte) signed integer) by default. See the help file
; for DllStructCreate for all types.
; An example: If you want to read a word that is 15 characters in
; length, you would use 'char[16]'.

; Note(s): Values returned are in Decimal format, unless specified as a 'char' type, then
; they are returned in ASCII format. Also note that size ('char[size]') for all
; 'char' types should be 1 greater than the actual size.
