- NAME
- link - make a hard link to a file
- SYNOPSIS
- #include <unistd.h>
- int link(const char *name1, const char *name2)
- DESCRIPTION
- A hard link to name1 is created; the link has the name name2. Name1 must
- exist.
- With hard links, both name1 and name2 must be in the same file system.
- Name1 must not be a directory. Both the old and the new link share equal
- access and rights to the underlying object.
- RETURN VALUE
- Upon successful completion, a value of 0 is returned. Otherwise, a value
- of -1 is returned and errno is set to indicate the error.
- ERRORS
- Link will fail and no link will be created if one or more of the
- following are true:
- [ENOTDIR] A component of either path prefix is not a directory.
- [ENAMETOOLONG] A path name exceeds PATH_MAX characters.
- [ENOENT] A component of either path prefix does not exist.
- [EACCES] A component of either path prefix denies search
- permission.
- [EACCES] The requested link requires writing in a directory with a
- mode that denies write permission.
- [ELOOP] Too many symbolic links were encountered in translating
- one of the pathnames. (Minix-vmd)
- [ENOENT] The file named by name1 does not exist.
- [EEXIST] The link named by name2 does exist.
- [EPERM] The file named by name1 is a directory and the effective
- user ID is not super-user.
- [EXDEV] The link named by name2 and the file named by name1 are on
- different file systems.

- LINK(2) Minix Programmer's Manual LINK(2)
- [ENOSPC] The directory in which the entry for the new link is being
- placed cannot be extended because there is no space left
- on the file system containing the directory.
- [EIO] An I/O error occurred while reading from or writing to the
- file system to make the directory entry.
- [EROFS] The requested link requires writing in a directory on a
- read-only file system.
- [EFAULT] One of the pathnames specified is outside the process's
- allocated address space.
