using ftw()
hello

im trying to find more information about the function: ftw()

however it seems every resource has the same thing
how to declare it and what it is supposed to do

does anyone know of a resource that actually has ftw used within a program, so i can get an idea of how to actually use it?

im concerned with such little documentation out there
if i should be using it or if there is a better way to search a directory hierarchy.

ftw function

int ftw(const char *path, int(*func)(), int depth); what does the third parameter(depth) mean? the book said that the larger the value of depth, the fewer directories have to be reopened, therefore increasing the speed of the call. how so? thanks (1 Reply)

ftw

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>.
