DPNS_READLINK(3)					      DPNS Library Functions						  DPNS_READLINK(3)

NAME

       dpns_readlink - read value of a symbolic link in the DPNS Name Server

SYNOPSIS

       #include <sys/types.h>
       #include "dpns_api.h"

       int dpns_readlink (const char *path, char *buf, size_t bufsiz)

DESCRIPTION

       dpns_readlink reads the value of a symbolic link in the DPNS Name Server.

       path   specifies the link name relative to the current DPNS directory or the full DPNS pathname.

       buf    points at a buffer to receive the value.

       bufsiz gives the buffer size.

RETURN VALUE

       This  routine returns the number of characters put in the buffer if the operation was successful or -1 if the operation failed. In the lat-
       ter case, serrno is set appropriately.

ERRORS

       ENOENT	    The named link does not exist or is a null pathname.

       EACCES	    Search permission is denied on a component of the path prefix.

       EFAULT	    path or buf is a NULL pointer.

       ENOTDIR	    A component of path prefix is not a directory.

       EINVAL	    path is not a symbolic link.

       ENAMETOOLONG The length of path exceeds CA_MAXPATHLEN or the length of a path component exceeds CA_MAXNAMELEN.

       SENOSHOST    Host unknown.

       SENOSSERV    Service unknown.

       SECOMERR     Communication error.

       ENSNACT	    Name server is not running or is being shutdown.

NAME

       dpns_symlink - make a symbolic link to a file or a directory in the DPNS Name Server

SYNOPSIS

       #include <sys/types.h>
       #include "dpns_api.h"

       int dpns_symlink (const char *target, const char *linkname)

DESCRIPTION

       dpns_symlink makes a symbolic link to a file or a directory in the DPNS Name Server.

       linkname
	      specifies the link name relative to the current DPNS directory or the full DPNS pathname.

RETURN VALUE

       This routine returns 0 if the operation was successful or -1 if the operation failed. In the latter case, serrno is set appropriately.

ERRORS

       ENOENT	    A component of linkname prefix does not exist.

       EACCES	    Search permission is denied on a component of linkname prefix or write permission on linkname parent directory is denied.

       EFAULT	    target or linkname is a NULL pointer.

       EEXIST	    linkname exists already.

       ENOTDIR	    A component of linkname prefix is not a directory.

       ENOSPC	    The name server database is full.

       ENAMETOOLONG The length of target or linkname exceeds CA_MAXPATHLEN or the length of a linkname component exceeds CA_MAXNAMELEN.

       SENOSHOST    Host unknown.

       SENOSSERV    Service unknown.

       SECOMERR     Communication error.

       SELOOP	    Too many symbolic links encountered when parsing linkname.

       ENSNACT	    Name server is not running or is being shutdown.
