Dear Members,
Do you know any information about versioning a binary file. That means test.out 1.0.0, 1.0.1, 1.1.0, and so on. Can I manually edit version number (both major and minor) and revision number myself (how?) or any utility to set version number (which one?).
Best Regards,

UNDELETE(2) BSD System Calls Manual UNDELETE(2)
NAME
undelete -- attempt to recover a deleted file
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <unistd.h>
int
undelete(const char *path);
DESCRIPTION
The undelete() system call attempts to recover the deleted file named by path. Currently, this works only when the named object is a white-
out in a union file system. The system call removes the whiteout causing any objects in a lower layer of the union stack to become visible
once more.
Eventually, the undelete() functionality may be expanded to other file systems able to recover deleted files such as the log-structured file
system.
RETURN VALUES
The undelete() function returns the value 0 if successful; otherwise the value -1 is returned and the global variable errno is set to indi-
cate the error.
ERRORS
The undelete() succeeds unless:
[ENOTDIR] A component of the path prefix is not a directory.
[ENAMETOOLONG] A component of a pathname exceeded 255 characters, or an entire path name exceeded 1023 characters.
[EEXIST] The path does not reference a whiteout.
[ENOENT] The named whiteout does not exist.
[EACCES] Search permission is denied for a component of the path prefix.
[EACCES] Write permission is denied on the directory containing the name to be undeleted.
[ELOOP] Too many symbolic links were encountered in translating the pathname.
[EPERM] The directory containing the name is marked sticky, and the containing directory is not owned by the effective user ID.
[EINVAL] The last component of the path is '..'.
[EIO] An I/O error occurred while updating the directory entry.
[EROFS] The name resides on a read-only file system.
[EFAULT] The path argument points outside the process's allocated address space.
SEE ALSO
unlink(2), mount_unionfs(8)
HISTORY
The undelete() system call first appeared in 4.4BSD-Lite.
BSD January 22, 2006 BSD
