## SYNOPSIS

1. stat = rawio.stat(filename)
2. stat = rawio.stat(fd)
3. stat = handle:stat()

## DESCRIPTION

The functions return information about a file. The first form takes a filename, the second uses an already open numeric file descriptor, while the third accesses an already open file handle.

## RETURN VALUE

On success, returns a table with the requested information. On failure, the forms one and two return three values: nil, a string describing the error (The result of the C library call strerror() on the errno code) and the errno number from the standard C library. Form three just returns nil on failure, the error can be retrieved using rawio:lastError().

Not all files have usable values in all fields. Network connections do not have a size, for example.

Field | Contents
--- | ---
atime | Time of last access, a datetime instance. Not supported by FAT filesystems.
blksize | Size of one block in the filesystem.
blocks | Number of filesystem blocks used by the file.
ctime | Time of last status change, a datetime instance.
mode | The filesystem mode bits. (TODO: readable, writable, directory)
mtime | Time of last modification, a datetime instance.
nlink | Number of hard links.
size | The size of the file in bytes.
