NAME fchmod, stat, fstat, lstat (stub function) - manipulate file status

SYNOPSIS

     #include <sys/types.h>
     #include <sys/stat.h>
     #include <sys/statx.h>

     int fchmod(const int filedes, const mode_t mode);
     int   stat(const char *path, struct stat *buf);
     int  fstat(int file_descriptor, struct stat *buf);
     int  lstat(const char *path, struct stat *buf);   /* forwarder fn */

DESCRIPTION
     fchmod() is the same a chmod(), only that it identifies files by a
     file descriptor filedes, a small non-negative integer returned by open().

     stat() is the same as in the emx library, plus two additional entries
     in struct stat: 

  u_long  st_blksize; 	/* preferred blocksize. */
  u_long  st_blocks; 	/* = st_size / st_blksize  */

     lstat() is the very same as stat() except when a symbolic link 
     is being specified: While stat() resolves the link, lstat() does 
     not dereference it.  

CONFORMING TO
    stat(), fstat() conforms to UNIX, since V7, and also to Posix 1.
    lstat() conforms to 4.2BSD and later and to SVr4, it appears in SUSV2.


IMPLEMENTATION 
     fchmod() has similar limits as chmod(), therefore read the relevant
     section in the EMX docs.

     We do not implement lstat(). However to be on the safe side for future 
     enhancements, we don't #define lstat to stat, even if by default OS/2
     filesystems do not support symbolic links: We create an entry point for 
     lstat() in libextensions instead!

  TODO
     A link database, a _posixRedirRoot() function to emulate a Posix file 
     system and real implementations. ;-)

LIMITATIONS
	Assumes HPFS (512 bytes) for st_blksize in fstat(). Use stat() instead;
	other file systems may be used.
