#include
int fstat(int handle, struct stat *statbuf);
int stat(const char *path, struct stat *statbuf);
int _wstat(const wchar_t *path, struct stat *statbuf);

Description

Gets open file information.

fstat stores information in the stat structure about the file or directory associated with handle.

stat stores information about a given file or directory in the stat structure. The name of the file is path.

statbuf points to the stat structure (defined in sys\stat.h). That structure contains the following fields:

st_mode Bit mask giving information about the file's mode
st_dev Drive number of disk containing the file or file handle if the file is on a device
st_rdev Same as st_dev
st_nlink Set to the integer constant 1
st_size Size of the file in bytes
st_atime Most recent access (Windows) or last time modified (DOS)
st_mtime Same as st_atime
st_ctime Same as st_atime

The stat structure contains three more fields not mentioned here. They contain values that are meaningful only in UNIX.

The st_mode bit mask that gives information about the mode of the open file includes the following bits:

One of the following bits will be set:

S_IFCHR If handle refers to a device.
S_IFREG If an ordinary file is referred to by handle.

One or both of the following bits will be set:

S_IWRITE If user has permission to write to file.
S_IREAD If user has permission to read to file.

The HPFS and NTFS file-management systems make the following distinctions:

st_atime Most recent access
st_mtime Most recent modify
st_ctime Creation time

Return Value

fstat and stat return if they successfully retrieved the information about the open file.

On error (failure to get the information) these functions return -1 and set the global variable errno
to

EBADF Bad file handle
