NAME¶
dpns_opendir - open a DPNS directory, having the specified GUID, in the name
server
SYNOPSIS¶
#include <sys/types.h>
#include "dpns_api.h"
dpns_DIR *dpns_opendir (const char *path, const char
*guid)
dpns_DIR *dpns_opendirxg (char *server, const char
*path, const char *guid)
DESCRIPTION¶
dpns_opendir opens a DPNS directory, having the specified GUID, in the
name server to be used in subsequent
dpns_readdir operations. A
dpns_DIR structure and a buffer to cache the directory entries are
allocated in the client API.
- guid
- specifies the Grid Unique IDentifier.
- path
- specifies the logical pathname relative to the current DPNS
directory or the full DPNS pathname.
RETURN VALUE¶
This routine returns a pointer to be used in the subsequent directory function
calls if the operation was successful or NULL 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 read permission is denied on path.
- EFAULT
- path is a NULL pointer.
- EINVAL
- The length of the guid component exceeds
CA_MAXGUIDLEN.
- 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
