int base int level
The <ftw.h> header shall define the following symbolic constants for use as values of the third argument to the application-supplied function that is passed as the second argument to ftw() and nftw():
- Non-directory file.
- Directory without read permission.
- Directory with subdirectories visited.
- Unknown type; stat() failed.
- Symbolic link.
- Symbolic link that names a nonexistent file.
The <ftw.h> header shall define the following symbolic constants for use as values of the fourth argument to nftw():
- Physical walk, does not follow symbolic links. Otherwise, nftw() follows links but does not walk down any path that crosses itself.
- The walk does not cross a mount point.
- All subdirectories are visited before the directory itself.
- The walk changes to each directory before reading it.
The following shall be declared as functions and may also be defined as macros. Function prototypes shall be provided.
int ftw(const char *, int (*)(const char *, const struct stat *, int), int); int nftw(const char *, int (*)(const char *, const struct stat *, int, struct FTW *), int, int);
The <ftw.h> header shall define 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 may also make visible all symbols from <sys/stat.h>.
The following sections are informative.
