@chapter Files and Directories

@section Directories

@subsection Format of Directory Entries

@subsection Directory Operations

@example

struct dirent, Type, Implemented

opendir(), Function, Implemented

readdir(), Function, Implemented

readdir_r(), Function, Implemented

rewinddir(), Function, Implemented

closedir(), Function, Implemented

@end example

@section Working Directory

@subsection Change Current Working Directory

@example

chdir(), Function, Implemented

@end example

@subsection Get Working Directory Pathname

@example

getcwd(), Function, Implemented

@end example

@section General File Creation

@subsection Open a File

@example

open(), Function, Implemented

O_RDONLY, Constant, Implemented

O_WRONLY, Constant, Implemented

O_RDWR, Constant, Implemented

O_APPEND, Constant, Implemented

O_CREAT, Constant, Implemented

O_DSYNC, Constant, Unimplemented

O_EXCL, Constant, Implemented

O_NOCTTY, Constant, Implemented

O_NONBLOCK, Constant, Implemented

@end example

NOTE: In the newlib fcntl.h, O_SYNC is defined only if _POSIX_SOURCE is

not defined.  This seems wrong.

@subsection Create a New File or Rewrite an Existing One

@example

creat(), Function, Implemented

@end example

@subsection Set File Creation Mask

@example

umask(), Function, Implemented

@end example

@subsection Link to a File

link(), Function, Implemented

@end example

@section Special File Creation

@subsection Make a Directory

@example

mkdir(), Function, Implemented

@end example

@subsection Make a FIFO Special File

@example

mkfifo(), Function, Untested Implementation

@end example

NOTE: mkfifo() is implemented but no filesystem supports FIFOs.

@section File Removal

@end example

@subsection Change File Modes

@example

chmod(), Function, Implemented

fchmod(), Function, Implemented

@end example

@subsection Change Owner and Group of a File

@example

chown(), Function, Implemented

@end example

@subsection Set File Access and Modification Times

include search patch is used to get the right one.  There are

conflicts between the newlib unistd.h and RTEMS' version.
