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>.
