_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>>.
