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 opera- tion 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. SEE ALSO

NAME
rfio_access - check existence/accessibility of a file/directory SYNOPSIS
Under Unix: #include <sys/types.h> #include <unistd.h> #include "rfio_api.h" Under Windows/NT: #include <sys/types.h> #define R_OK 4 #define W_OK 2 #define X_OK 1 #define F_OK 0 #include "rfio_api.h" int rfio_access (const char *path, int amode); DESCRIPTION
rfio_access checks the existence or the accessibility of the file/directory path according to the bit pattern in amode using the real user ID. path specifies the logical pathname relative to the current directory or the full pathname. amode the bit pattern is built by an OR of the constants defined in <unistd.h> under Unix or to be explicitly defined under Windows/NT: R_OK test for read permission W_OK test for write permission X_OK test for search/execute permission F_OK test for existence of the directory/file. RETURN VALUE
This routine returns 0 if the operation was successful or -1 if the operation failed. In the latter case, serrno is set appropriately. ERRORS
ENOENT The named file/directory does not exist. EACCES Search permission is denied on a component of the path prefix or specified access to the file itself is denied. EFAULT path is a NULL pointer. ENOTDIR A component of path prefix is not a directory. EINVAL amode is invalid. 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. SEE ALSO
