/* Reentrant version of gettimeofday system call

   This implementation just calls the times/gettimeofday system calls.
3
   Gettimeofday may not be available on all targets.  It's presence

   here is dubious.  Consider it for internal use only.  */

DESCRIPTION
54
        This is a reentrant version of <<gettimeofday>>.  It
55
        takes a pointer to the global data block, which holds
56
        <<errno>>.
57
 
58
        This function is only available for a few targets.
59
        Check libc.a to see if its available on yours.
