original csymlink.2 massaged, nroffed and htmlized.
SYNOPSIS csymlink(ucb_target, att_target, linkname) char *ucb_target, *att_target, *linkname; DESCRIPTION A conditional symbolic link linkname is created to ucb_target and att_target. (Linkname is the name of the file created; the target strings are used to create the conditional symbolic link.) Any of the names may be an arbitrary path name; the files need not be on the same file system. When a conditional symbolic link is encountered during pathname pars- ing, the link is treated as an ordinary symbolic link. However, the value of the link depends on the process's selected universe (U_UCB or U_ATT). If the universe is U_UCB, the value of the symbolic link is ucb_target. If the universe is U_ATT, the value of the symbolic link is att_target. 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 conditional symbolic link is made unless one or more of the follow- ing are true: [EPERM] Any of the arguments contain a character with the high- order bit set. [ENOENT] One of the pathnames specified was too long. [ENOTDIR] A component of the linkname prefix is not a directory. [EEXIST] Linkname already exists. [EACCES] A component of the linkname path prefix denies search permission. [EROFS] The file linkname would reside on a read-only file sys- tem. [EFAULT] Any of the parameters point outside the process's allo- cated address space. [ELOOP] Too may symbolic links were encountered in translating the pathname. [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 direc- tory.
