SYNOPSIS

#include <fd.h>

fd_stat(path, buf)
char ∗path;
struct fdstat ∗buf;

DESCRIPTION

Fd_stat returns information about the file or directory specified by path. Buf is a pointer to an fdstat structure, into which fd_stat returns information. 

struct fdstat {
longfdst_mode; /∗ file type ∗/
fdoff_tfdst_size;/∗ file size in bytes ∗/
fdaddr_tfdst_daddr; /∗ starting block number of file within fs ∗/
longfdst_mtime; /∗ modification time ∗/
intfdst_uid;/∗ creator’s UID ∗/
};
 /∗
 ∗ bit fields in fdst_mode
 ∗/
#define FDS_IFMT0xF0/∗ mask for file-type field ∗/
#define  FDS_IFREG0x10 /∗ regular file ∗/
#define  FDS_IFDIR0x20/∗ directory file ∗/

RETURN VALUE

A 0 value is returned if the operation succeeds; otherwise fd_stat returns -1 and the global variable errno indicates the reason for the failure. 

ERRORS

[ENOTDIR] A component of the path prefix is not a directory. 

[ENOENT] Path does not exist. 

[EIO] An I/O error occurred while making the directory entry or allocating space.
