ftw.h

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 sec-
       ond 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>.
