@node _dos_getfileattr, dos
@subheading Syntax

@example
#include <dos.h>

unsigned int _dos_getfileattr(const char *filename, unsigned int *p_attr);
@end example

@subheading Description

This function determines the attributes of given file and fills @var{attr}
with it. Use the following constans (in DOS.H) to check this value.

@table @code

@item _A_NORMAL (0x00)

Normal file (no read/write restrictions)

@item _A_RDONLY (0x01)

Read only file

@item _A_HIDDEN (0x02)

Hidden file

@item _A_SYSTEM (0x04)

System file

@item _A_VOLID (0x08)

Volume ID file

@item _A_SUBDIR (0x10)

Subdirectory

@item _A_ARCH (0x20)

Archive file

@end table

@xref{_dos_setfileattr}.

This function does not support long filenames, even on systems where the
LFN API (@pxref{_use_lfn, LFN}) is available.  For LFN-aware functions
with similar functionality see @ref{_chmod}.  Also see @ref{chmod},
@ref{access}, and @ref{stat}, which are Posix-standard.

@subheading Return Value

Returns with 0 if successful and DOS error value on error (and sets
@var{errno}=ENOENT).

@subheading Portability

@portability !ansi, !posix

@{
  puts("FOO.DAT attributes are:");
  if ( attr & _A_ARCH )   puts("Archive");
  if ( attr & _A_RDONLY ) puts("Read only");
  if ( attr & _A_HIDDEN ) puts("Hidden");
  if ( attr & _A_SYSTEM ) puts("Is it part of DOS ?");
  if ( attr & _A_VOLID )  puts("Volume ID");
  if ( attr & _A_SUBDIR ) puts("Directory");
@}
else
  puts("Unable to get FOO.DAT attributes.");
