RFIO_OPENDIR(3)
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 pathname.
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 directories 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 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.
