minix/lib/syslib/sys_vinl.c
Ben Gras 9df1183b94 . removed const from putenv() for g++
. added safecopies.c:
  these are library functions to maintain grant tables in own address space
. sys_safecopy.c:
  interfaces to kernel calls to perform safe copy functions in from or to
  foreign process
. changes in i/o fields (type merged with request) reflected in
  library functions (sys_out.c, sys_vinb.c, sys_vinl.c, sys_vinw.c,
  sys_voutb.c, sys_voutl.c, sys_voutw.c)
. type merged with request in sys_sdevio, also now accepts offset which
  is used when a grant is specified (the _DIO_SAFE subtype)
. system printf() function changed to send DIAGNOSTICS_S messages, which
  specify a grant id instead of a direct address for the buffer to be
  printed; tty and log can then safecopy the buffer
