rfio_opendir - open a directory
#include <sys/types.h> #include "rfio_api.h" RDIR *rfio_opendir (const char *path);
rfio_opendir opens a directory to be used in subsequent rfio_readdir operations. A RDIR structure and a buffer to cache the directory entries are allocated in the client API. path specifies the logical pathname relative to the current directory or the full pathname.
For LCG directories, a multi-threaded application will need to initialize itself the Cthread (LCG Thread Interface) library ; this is done by including "shift/Cthread_api.h" and calling the function Cthread_init() at the beginning. Otherwise accessing LCG directories will not be thread-safe. See Cthread(3).
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.
