SYMLINK(2)			     BSD System Calls Manual			       SYMLINK(2)

NAME
     symlink -- make symbolic link to a file

SYNOPSIS
     #include <unistd.h>

     int
     symlink(const char *name1, const char *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 VALUES
     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 succeeds unless:

     [ENOTDIR]		A component of the name2 prefix is not a directory.

     [ENAMETOOLONG]	A component of a pathname exceeded {NAME_MAX} characters, or an entire
			path name exceeded {PATH_MAX} 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 sys-
			tem 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.
