+	_fstat_r
+
+ANSI_SYNOPSIS

+		     int <[fd]>, struct stat *<[pstat]>);
+
+TRAD_SYNOPSIS
+	#include <reent.h>
+	int _fstat_r(<[ptr]>, <[fd]>, <[pstat]>)
+	struct _reent *<[ptr]>;
+	int <[fd]>;
+	struct stat *<[pstat]>;
+
+DESCRIPTION
+	This is a reentrant version of <<fstat>>.  It
+	takes a pointer to the global data block, which holds
+	<<errno>>.
