NAME

rfio_opendir - open a directory

SYNOPSIS

#include <sys/types.h> #include "rfio_api.h" RDIR *rfio_opendir (const char *path);

DESCRIPTION

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 path‐ name.

NOTES

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 directo‐ ries will not be thread-safe. See Cthread(3).

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 permis‐ sion 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.
