LINK(2) System Calls Manual LINK(2) NAME link, symlink, readlink - link to a file SYNOPSIS int link(name1, name2) char *name1, *name2; int symlink(name1, name2) char *name1, *name2; int readlink(name, buf, size) char *name, *buf; DESCRIPTION Link and symlink create a link to file name1 with new name name2. Ei- ther name may be an arbitrary path name. After link, name2 is entirely equivalent to name1; it is a directory entry referring to the same file as name1. Only the super-user can make the link if name1 is a directory. After symlink, name2 is a new symbolic link; when it is encountered in any path name, name1 is substituted for name2, and path name parsing continues. If name1 begins with the character, it is interpreted with respect to the root directory; if not, it is interpreted with respect to the directory in which name2 resides. Symbolic links are slightly slower than normal links but may span file systems; normal links are confined to a single file system. Readlink copies the pathname inside symbolic link name into memory at buf. No more than size bytes are copied; the actual number of bytes read is returned. The contents of buf will not be null-terminated. An error is returned if name is not a symbolic link.
