lfc_DIR *lfc_opendir (const char *path)

lfc_opendir opens a LFC directory in the name server to be used in subsequent lfc_readdir operations. A lfc_DIR structure and a buffer to cache the directory entries are allocated in the client API.

path

specifies the logical pathname relative to the current LFC directory or the full LFC pathname.

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.

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.

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.
