SYMLINK(2)SYMLINK(2)NAMEsymlink - make symbolic link to a file
SYNOPSIS
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.
RETURN VALUE
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.
ERRORS
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.
[EINVAL] Either name1 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 path name exceeded 1023
characters.
[ENOENT] The named file does not exist.
[EACCES] A component of the name2 path prefix denies search
permission.
[ELOOP] Too many symbolic links were encountered in translating
the pathname.
[EEXIST] Name2 already exists.
[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.
[EROFS] The file name2 would reside on a read-only file system.
[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
there is no space left 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 symbolic link is being created has been exhausted.
[EIO] An I/O error occurred while making the directory entry
or allocating the inode.
[EFAULT] Name1 or name2 points outside the process's allocated
address space.
