39.Sh NAME
40.Nm symlink
41.Nd make symbolic link to a file
42.Sh LIBRARY
43.Lb libc
44.Sh SYNOPSIS
45.In unistd.h
46.Ft int
47.Fn symlink "const char *name1" "const char *name2"
48.Sh DESCRIPTION
49A symbolic link
50.Fa name2
51is created to
52.Fa name1
53.Pf ( Fa name2
54is the name of the
55file created,
56.Fa name1
57is the string
58used in creating the symbolic link).
59Either name may be an arbitrary path name; the files need not
60be on the same file system.
61.Sh RETURN VALUES
62.Rv -std symlink
63.Sh ERRORS
64The symbolic link succeeds unless:
65.Bl -tag -width Er
66.It Bq Er ENOTDIR
67A component of the
68.Fa name2
69prefix is not a directory.
70.It Bq Er ENAMETOOLONG
71A component of either pathname exceeded 255 characters,
72or the entire length of either path name exceeded 1023 characters.
73.It Bq Er ENOENT
74The named file does not exist.
75.It Bq Er EACCES
76A component of the
77.Fa name2
78path prefix denies search permission.
79.It Bq Er ELOOP
80Too many symbolic links were encountered in translating the pathname.
81.It Bq Er EEXIST
82.Fa Name2
83already exists.
84.It Bq Er EIO
85An I/O error occurred while making the directory entry for
86.Fa name2 ,
87or allocating the inode for
88.Fa name2 ,
89or writing out the link contents of
90.Fa name2 .
91.It Bq Er EROFS
92The file
93.Fa name2
94would reside on a read-only file system.
95.It Bq Er ENOSPC
96The directory in which the entry for the new symbolic link is being placed
97cannot be extended because there is no space left on the file
98system containing the directory.
99.It Bq Er ENOSPC
100The new symbolic link cannot be created because
101there is no space left on the file
102system that will contain the symbolic link.
103.It Bq Er ENOSPC
104There are no free inodes on the file system on which the
105symbolic link is being created.
106.It Bq Er EDQUOT
107The directory in which the entry for the new symbolic link
108is being placed cannot be extended because the
109user's quota of disk blocks on the file system
110containing the directory has been exhausted.
111.It Bq Er EDQUOT
112The new symbolic link cannot be created because the user's
113quota of disk blocks on the file system that will
114contain the symbolic link has been exhausted.
115.It Bq Er EDQUOT
116The user's quota of inodes on the file system on
117which the symbolic link is being created has been exhausted.
118.It Bq Er EIO
119An I/O error occurred while making the directory entry or allocating the inode.
120.It Bq Er EFAULT
121.Fa Name1
122or
123.Fa name2
124points outside the process's allocated address space.
