symlink(2)
NAME
symlink − make symbolic link to a file
SYNTAX
symlink(name1, name2)
char *name1, *name2;
DESCRIPTION
A symbolic link name2 is created to name1 (name2 is the name of the file created, name1 is the string used in creating the symbolic link). Either name may be an arbitrary path name; the files need not be on the same file system.
Upon successful completion, a zero value is returned. If an error occurs, the error code is stored in errno and a −1 value is returned.
DIAGNOSTICS
The symbolic link is made unless on or more of the following are true:
[ENOTDIR] A component of the name2 prefix is not a directory.
[EEXIST] Name2 already exists.
[EACCES] A component of the name2 path prefix denies search permission.
[EROFS] The file name2 would reside on a read-only file system.
[EFAULT] Name1 or name2 points outside the process’s allocated address space.
[ELOOP] Too many symbolic links were encountered in translating the pathname.
[EINVAL] Either name or name2 contains a character with the high-order bit set.
[ENAMETOOLONG]
A component of either pathname exceeded 255 characters, or the entire length of either pathname exceeded 1023 characters.
[ENOENT] The named file does not exist.
[EIO] An I/O error occurred while making the directory entry for name2, or allocating the inode for name2, or writing out the link contents of name2.
[ENOSPC] The directory in which the entry for the new symbolic link is being placed cannot be extended because there is no space left on the file system containing the directory.
[ENOSPC] The new symbolic link cannot be created because there is no space elft on the file system that will contain the symbolic link.
[ENOSPC] There are no free inodes on the file system on which the symbolic link is being created.
[EDQUOT] The directory in which the entry for the new symbolic link is being placed cannot be extended because the user’s quota of disk blocks on the file system containing the directory has been exhausted.
[EDQUOT] The new symbolic link cannot be created because the user’s quota of disk blocks on the file system that will contain the symbolic link has been exhausted.
[EDQUOT] The user’s quota of inodes on the file system on which the user’s symbolic link is being created has been exhausted.
[EIO] An I/O error occurred while making the directory entry or allocating the inode.
[ETIMEDOUT] A "connect" request or remote file operation failed because the connected party did not properly respond after a period of time which is dependent on the communications protocol.
