NAME
dpns_statg - get information about a DPNS file or directory in the name server SYNOPSIS
#include <sys/types.h> #include "dpns_api.h" int dpns_statg (const char *path, const char *guid, struct dpns_filestatg *statbuf) int dpns_statr (const char *sfn, struct dpns_filestatg *statbuf) DESCRIPTION
dpns_statg gets information about a DPNS file or directory, having the given GUID, in the name server. dpns_statr retrieves information about the given replica. The file can be specified by path name or by guid. If both are given, they must point at the same file. guid specifies the Grid Unique IDentifier. path specifies the logical pathname relative to the current DPNS directory or the full DPNS pathname. sfn is either the Site URL or the Physical File Name for the replica. The structure pointed to by statbuf contains the following members: u_signed64 fileid; /* entry unique identifier */ char guid[CA_MAXGUIDLEN+1] /* GUID */ mode_t filemode; /* see below */ int nlink; /* number of files in a directory */ uid_t uid; gid_t gid; u_signed64 filesize; time_t atime; /* last access to file */ time_t mtime; /* last file modification */ time_t ctime; /* last metadata modification */ short fileclass; /* 1--> experiment, 2 --> user */ char status; /* '-' --> online, 'm' --> migrated */ char csumtype[3]; char csumvalue[33]; filemode is constructed by OR'ing the bits defined in <sys/stat.h> under Unix or "statbits.h" under Windows/NT: S_IFLNK 0xA000 symbolic link S_IFREG 0x8000 regular file S_IFDIR 0x4000 directory S_ISUID 0004000 set user ID on execution S_ISGID 0002000 set group ID on execution S_ISVTX 0001000 sticky bit S_IRUSR 0000400 read by owner S_IWUSR 0000200 write by owner S_IXUSR 0000100 execute/search by owner S_IRGRP 0000040 read by group S_IWGRP 0000020 write by group S_IXGRP 0000010 execute/search by group S_IROTH 0000004 read by others S_IWOTH 0000002 write by others S_IXOTH 0000001 execute/search by others 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/directory does not exist or is a null pathname. EACCES Search permission is denied on a component of the path prefix. EFAULT path or statbuf is a NULL pointer. EINVAL The length of the guid component exceeds CA_MAXGUIDLEN or path and guid are both given and they point at a different file. 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 or the length of the sfn exceeds CA_MAXSFNLEN. SENOSHOST Host unknown. SENOSSERV Service unknown. SECOMERR Communication error. ENSNACT Name server is not running or is being shutdown. SEE ALSO

NAME
dpns_stat - get information about a DPNS file or directory in the name server SYNOPSIS
#include <sys/types.h> #include "dpns_api.h" int dpns_lstat (const char *path, struct dpns_filestat *statbuf) int dpns_stat (const char *path, struct dpns_filestat *statbuf) int dpns_statx (const char *path, struct dpns_fileid *file_uniqueid, struct dpns_filestat *statbuf) DESCRIPTION
dpns_stat gets information about a DPNS file or directory in the name server. dpns_lstat is identical to dpns_stat except for symbolic links. dpns_lstat retrieves information about the link itself, while dpns_stat gets information about the file/directory referenced by the symbolic link. dpns_statx returns the same information plus the file unique id (name server hostname and file id). The file can be specified by path name or by file_uniqueid. If both are given, file_uniqueid is used. path specifies the logical pathname relative to the current DPNS directory or the full DPNS pathname. The structure pointed to by statbuf contains the following members: u_signed64 fileid; /* entry unique identifier */ mode_t filemode; /* see below */ int nlink; /* number of files in a directory */ uid_t uid; gid_t gid; u_signed64 filesize; time_t atime; /* last access to file */ time_t mtime; /* last file modification */ time_t ctime; /* last metadata modification */ short fileclass; /* 1--> experiment, 2 --> user */ char status; /* '-' --> online, 'm' --> migrated */ filemode is constructed by OR'ing the bits defined in <sys/stat.h> under Unix or "statbits.h" under Windows/NT: S_IFLNK 0xA000 symbolic link S_IFREG 0x8000 regular file S_IFDIR 0x4000 directory S_ISUID 0004000 set user ID on execution S_ISGID 0002000 set group ID on execution S_ISVTX 0001000 sticky bit S_IRUSR 0000400 read by owner S_IWUSR 0000200 write by owner S_IXUSR 0000100 execute/search by owner S_IRGRP 0000040 read by group S_IWGRP 0000020 write by group S_IXGRP 0000010 execute/search by group S_IROTH 0000004 read by others S_IWOTH 0000002 write by others S_IXOTH 0000001 execute/search by others RETURN VALUE
