Enumeration Type Documentation

anonymous enum

anonymous enum

Values for the FLAG argument to the user function passed to 'ftw' and 'nftw'.

Enumerator
FTW_F	Regular file.
FTW_F	Regular file.
FTW_D	Directory.
FTW_D	Directory.
FTW_DNR	Unreadable directory.
FTW_DNR	Unreadable directory.
FTW_NS	Unstatable file.
FTW_NS	Unstatable file.
FTW_SL	Symbolic link.
FTW_SL	Symbolic link.
FTW_DP	Directory, all subdirs have been visited.
FTW_DP	Directory, all subdirs have been visited.

anonymous enum

anonymous enum

Return values from callback functions.

Enumerator
FTW_CONTINUE	Continue with next sibling or for FTW_D with the first child.
FTW_CONTINUE	Continue with next sibling or for FTW_D with the first child.
FTW_STOP	Return from 'ftw' or 'nftw' with FTW_STOP as return value.
FTW_STOP	Return from 'ftw' or 'nftw' with FTW_STOP as return value.
FTW_SKIP_SUBTREE	Only meaningful for FTW_D: Don't walk through the subtree, instead just continue with its next sibling.
FTW_SKIP_SUBTREE	Only meaningful for FTW_D: Don't walk through the subtree, instead just continue with its next sibling.
FTW_SKIP_SIBLINGS	Continue with FTW_DP callback for current directory (if FTW_DEPTH) and then its siblings.
FTW_SKIP_SIBLINGS	Continue with FTW_DP callback for current directory (if FTW_DEPTH) and then its siblings.

anonymous enum

anonymous enum

Flags for fourth argument of 'nftw'.

Enumerator
FTW_PHYS	Perform physical walk, ignore symlinks.
FTW_PHYS	Perform physical walk, ignore symlinks.
FTW_MOUNT	Report only files on same file system as the argument.
FTW_MOUNT	Report only files on same file system as the argument.
FTW_CHDIR	Change to current directory while processing it.
FTW_CHDIR	Change to current directory while processing it.
FTW_DEPTH	Report files in directory before directory itself.
FTW_DEPTH	Report files in directory before directory itself.
FTW_ACTIONRETVAL	Assume callback to return FTW_* values instead of zero to continue and non-zero to terminate.
