<<_gettimeofday_r>>---Reentrant version of gettimeofday

_gettimeofday_r
SYNOPSIS
#include <reent.h>
#include <time.h>
int _gettimeofday_r(struct _reent *<[ptr]>,
struct timeval *<[ptimeval]>,
void *<[ptimezone]>);
DESCRIPTION
This is a reentrant version of <<gettimeofday>>. It
takes a pointer to the global data block, which holds
<<errno>>.
This function is only available for a few targets.
Check libc.a to see if its available on yours.
