NAME

       dpns_accessr - check existence/accessibility of a file replica

SYNOPSIS

       Under Unix:
       #include <sys/types.h>
       #include <unistd.h>
       #include "dpns_api.h"

       Under Windows/NT:
       #include <sys/types.h>
       #define R_OK 4
       #define W_OK 2
       #define X_OK 1
       #define F_OK 0
       #include "dpns_api.h"

       int dpns_accessr (const char *sfn, int amode);

DESCRIPTION

       dpns_accessr  checks in the name server database the existence or the accessibility of the file replica sfn according to the bit pattern in
       amode using the real user ID.

       sfn    is either the Site URL or the Physical File Name for the replica.

       amode  the bit pattern is built by an OR of the constants defined in <unistd.h> under Unix or to be explicitly defined under Windows/NT:

	      R_OK   test for read permission

	      W_OK   test for write permission

	      X_OK   test for search/execute permission

	      F_OK   test for existence of the file.

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	    The named file does not exist.

       EACCES	    Search permission is denied on a component of the parent file prefix, the specified access to the file  itself  is	denied	or
		    W_OK is requested but the replica status is not 'P' (cannot modify an existing file).

       EFAULT	    sfn is a NULL pointer.

       EINVAL	    amode is invalid.

       ENAMETOOLONG The length of sfn exceeds CA_MAXSFNLEN.

       SENOSHOST    Host unknown.

       SENOSSERV    Service unknown.

       SECOMERR     Communication error.

       ENSNACT	    Name server is not running or is being shutdown.

NAME

       dpns_modreplica - modify information about a given replica

SYNOPSIS

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

       int dpns_modreplica (const char *sfn, const char *setname, const char *poolname, const char *server)

       int dpns_modreplicax (const char *sfn, const char *setname, const char *poolname, const char *server, const char *fs, const char r_type)

DESCRIPTION

       dpns_modreplica modifies information about a given replica.

       sfn    is either the Site URL or the Physical File Name for the replica.

       setname
	      is either a replica set name or a space token.

       server is either the Storage Element fully qualified hostname or the disk server.

       poolname
	      specifies the disk pool name (this argument is only meaningful for the Disk Pool Manager).

       dpns_modreplicax
	      is similar to dpns_modreplica but has the additional arguments:

       fs     specifies the mount point of the dedicated filesystem (this argument is only meaningful for the Disk Pool Manager).

       r_type may be one of the following:

	      P      Primary

	      S      Secondary.

RETURN VALUE

       These routines return 0 if the operation was successful or -1 if the operation failed. In the latter case, serrno is set appropriately.

ERRORS

       ENOENT	    The named replica does not exist.

       EACCES	    Search  permission	is  denied on a component of the parent directory or the effective user ID does not match the owner of the
		    file or read permission on the file entry itself is denied.

       EFAULT	    sfn is a NULL pointer.

       EINVAL	    The length of setname exceeds 36, the length of poolname exceeds CA_MAXPOOLNAMELEN or the length of server exceeds CA_MAXHOST-
		    NAMELEN.

       ENAMETOOLONG The length of sfn exceeds CA_MAXSFNLEN.

       SENOSHOST    Host unknown.

       SENOSSERV    Service unknown.

       SECOMERR     Communication error.

       ENSNACT	    Name server is not running or is being shutdown.
