FTW.H(3HEAD) Headers FTW.H(3HEAD)

NAME

ftw.h, ftw - file tree traversal

SYNOPSIS

#include <ftw.h>

DESCRIPTION

The <ftw.h> header defines the FTW structure that includes the
following members:

int base
int level


The <ftw.h> header defines macros for use as values of the third
argument to the application-supplied function that is passed as the
second argument to ftw() and nftw() (see ftw(3C)):

FTW_F
file


FTW_D
directory


FTW_DNR
directory without read permission


FTW_DP
directory with subdirectories visited


FTW_NS
unknown type; stat() failed


FTW_SL
symbolic link


FTW_SLN
symbolic link that names a nonexistent file


The <ftw.h> header defines macros for use as values of the fourth
argument to nftw():

FTW_PHYS
Physical walk, does not follow symbolic links.
Otherwise, nftw() follows links but does not walk down
any path that crosses itself.


FTW_MOUNT
The walk does not cross a mount point.


FTW_DEPTH
All subdirectories are visited before the directory
itself.


FTW_CHDIR
The walk changes to each direct ory before reading it.


The <ftw.h> header defines the stat structure and the symbolic names
for st_mode and the file type test macros as described in
<sys/stat.h>.


Inclusion of the <ftw.h> header might also make visible all symbols
from <sys/stat.h>.
