symlink

SYMLINK(2)							System Calls Manual							SYMLINK(2)

NAME

       symlink - 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  sym-
		      bolic 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.
