FUNCTION
	<<_stat_r>>---Reentrant version of stat
 
INDEX
	_stat_r
 
ANSI_SYNOPSIS
	#include <reent.h>
	int _stat_r(struct _reent *<[ptr]>,
		    const char *<[file]>, struct stat *<[pstat]>);
 
TRAD_SYNOPSIS
	#include <reent.h>
	int _stat_r(<[ptr]>, <[file]>, <[pstat]>)
	struct _reent *<[ptr]>;
	char *<[file]>;
	struct stat *<[pstat]>;
 
DESCRIPTION
	This is a reentrant version of <<stat>>.  It
	takes a pointer to the global data block, which holds
	<<errno>>.
