Get file status.
_________________________________________________________________
SYNTAX
#include <sys/types.h>
#include <sys/stat.h>
int stat (path, buffer_ptr)
char * path;
struct stat * buffer_ptr;
PARAMETERS
path Address of a pathname.
buffer_ptr Address of a stat buffer to fill.
DESCRIPTION
Stat returns the current attributes of the file named by the
pathname pointed to by <path> into the stat buffer at the
location specified by <buffer_ptr>. If <path> refers to a
symbolic link, file status for the target of the symbolic link is
returned.
The interpretation of the file's attributes depends on the file's
type (see stat(5)). The subject file must be of type `ordinary-
disk-file', `directory', `block-special-file', `character-
special-file', or `fifo-special-file'.
If stat fails, the contents of the buffer are undefined.
ACCESS CONTROL
Read, write, or execute permission of the named file is not
required, but the process must have permission to resolve <path>.
RETURN VALUE
0 The stat operation was successful.

-1 An error occurred. Errno is set to indicate the
error.
EXCEPTIONS
Errno may be set to one of the following error codes:
EFAULT <Buffer_ptr> points to an invalid address.
ENOENT The file the pathname resolved to does not exist.
ENOENT A non-terminal component of the pathname does not
exist.
ENOTDIR A non-terminal component of the pathname was not a
directory or symbolic link.
ENAMETOOLONG The pathname exceeds the length limit for
pathnames.
ENAMETOOLONG A component of the pathname exceeds the length
limit for filenames.
ENOMEM There are not enough system resources to resolve
the pathname or to expand a symbolic link.
ELOOP The number of symbolic links encountered during
pathname resolution exceeded MAXSYMLINKS. A
symbolic link cycle is suspected.
EPERM The pathname contains a character not in the
allowed character set.
EFAULT The pathname does not completely reside in the
process's address space or the pathname does not
terminate in the process's address space.
