NAME
dpns_creat - create a new DPNS file or reset it in the name server SYNOPSIS
#include <sys/types.h> #include "dpns_api.h" int dpns_creat (const char *path, mode_t mode) int dpns_creatx (const char *path, mode_t mode, struct dpns_fileid *file_uniqueid) DESCRIPTION
dpns_creat creates a new DPNS file or resets it in the name server. If the file exists, the length is truncated to 0 and the mode and owner are unchanged. If the file does not exist yet, an entry is created in the name server database and the file's owner ID is set to the effective user ID of the requestor. The group ID of the file is set to the effective group ID of the requestor or is taken from the parent directory if the latter has the S_ISGID bit set. The access permission bits for the file are taken from mode, then all bits set in the requestor's file mode creation mask are cleared (see dpns_umask(3)). dpns_creatx behaves in the same way and returns the file unique id (name server hostname and file id). path specifies the logical pathname 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 path prefix does not exist or path is a null pathname. EACCES Search permission is denied on a component of the path prefix or the file does not exist and write permission on the parent directory is denied or the file exists and write permission on the file itself is denied. EFAULT path or file_uniqueid is a NULL pointer. EEXIST File exists already and has replicas. ENOTDIR A component of path prefix is not a directory. EISDIR path is an existing directory. EINVAL The fileclass in the parent directory is zero. ENOSPC The name server database is full. 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. SEE ALSO

NAME
dpns_setfsize - set filesize for a regular file; set also last modification time to the current time SYNOPSIS
#include <sys/types.h> #include "dpns_api.h" int dpns_setfsize (const char *path, struct dpns_fileid *file_uniqueid, u_signed64 filesize) int dpns_setfsizec (const char *path, struct dpns_fileid *file_uniqueid, u_signed64 filesize, const char *csumtype, char *csumvalue) DESCRIPTION
dpns_setfsize sets the filesize for a regular file; set also the last modification time to the current time. This function should only be called by the stager after the last write operation has been performed on the file. The file can be identified by path name or by file_uniqueid. If both are specified, file_uniqueid is used. path specifies the logical pathname relative to the current DPNS directory or the full DPNS pathname. csumtype specifies the type of checksum. Valid types are: CS standard 32 bits checksum AD Adler 32 bits checksum MD MD5 128 bits checksum 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 path prefix does not exist or path is a null pathname. EACCES Search permission is denied on a component of the path prefix or the caller effective user ID does not match the owner ID of the file or write permission on the file itself is denied. EFAULT path and file_uniqueid are NULL pointers. ENOTDIR A component of path prefix is not a directory. EISDIR The file is not a regular file. EINVAL The length of the csumtype exceeds 2 or csumtype is an unknown type or the length of the csumvalue exceeds 32. 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. SEE ALSO
