+
+ANSI_SYNOPSIS
+	#include <reent.h>
+	#include <time.h>
+	int _gettimeofday_r(struct _reent *<[ptr]>,

+		void *<[ptimezone]>);
+
+TRAD_SYNOPSIS
+	#include <reent.h>
+	#include <time.h>
+	int _gettimeofday_r(<[ptr]>, <[ptimeval]>, <[ptimezone]>)
+	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.
