dpns_undelete - recover a logically deleted DPNS file entry in the name server
#include <sys/types.h> #include "dpns_api.h" int dpns_undelete (const char *path)
dpns_undelete recovers a DPNS file entry logically deleted by dpns_delete. This can be done as long as a the reclaim utility has not been run on the corresponding tape volume. path specifies the logical pathname relative to the current DPNS directory or the full DPNS pathname.
This routine returns 0 if the operation was successful or -1 if the operation failed. In the latter case, serrno is set appropriately.
EPERM path is a directory. ENOENT The named file does not exist or is a null pathname. EACCES Search permission is denied on a component of the path prefix or write permission is denied on the parent directory or the parent has the sticky bit S_ISVTX set and the effective user ID of the requestor does not match the owner ID of the file and the effective user ID of the requestor does not match the owner ID of the directory and the file is not writable by the requestor and the requestor does not have ADMIN privilege in the Cupv database. EFAULT path is a NULL pointer. ENOTDIR A component of path prefix is not a directory. 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.
