dpns_DIR *dpns_opendir (const char *path)

Description

dpns_opendir opens a DPNS directory 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.
path
specifies the logical pathname relative to the current DPNS directory or the full DPNS pathname.
