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>. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Interface Stability |Standard | +-----------------------------+-----------------------------+ SEE ALSO
