C 5 symlink - make symbolic link to a file

symlink(name1, name2)
char *name1, *name2;

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. The symbolic link is made unless on or more of the following are true:

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

15 [EINVAL] Either name1 or name2 contains a character with the high-order bit set.

15 [ENAMETOOLONG] A component of either pathname exceeded 255 characters, or the entire length of either path name exceeded 1023 characters.

15 [ENOENT] The named file does not exist.

15 [EACCES] A component of the name2 path prefix denies search permission.

15 [ELOOP] Too many symbolic links were encountered in translating the pathname.

15 [EEXIST] Name2 already exists.

15 [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.

15 [EROFS] The file name2 would reside on a read-only file system.

15 [EFAULT] Name1 or name2 points outside the process's allocated address space.
