TXNetSystem is an extension of TNetSystem able to deal with new
xrootd servers. The class detects the nature of the server and
redirects the calls to TNetSystem in case of a rootd server.
TXNetSystem() : TNetSystem()
Create system management class without connecting to server.
TXNetSystem(const char *url) : TNetSystem()
Create system management class and connect to server specified by url.
~TXNetSystem()
Destructor
void InitXrdClient()
One-time initialization of some communication variables for xrootd protocol
void* OpenDirectory(const char* dir)
Open a directory. Returns a non-zero pointer (with no special
purpose) in case of success, 0 in case of error.
void FreeDirectory(void *dirp)
Free(Close) the directory referenced by dirp
Int_t MakeDirectory(const char* dir)
Create a directory. Return 0 on success, -1 otherwise.
const char* GetDirEntry(void *dirp)
Get directory entry for directory referenced by dirp.
Returns 0 in case there are no more entries.
Int_t GetPathInfo(const char* path, FileStat_t &buf)
Get info about a file. Info is returned in the form of a FileStat_t
structure (see TSystem.h).
The function returns 0 in case of success and 1 if the file could
not be stat'ed.
NOTICE: Not all information is available with an xrootd server.
Bool_t ConsistentWith(const char *path, void *dirptr)
Check consistency of this helper with the one required
by 'path' or 'dirptr'.
Bool_t AccessPathName(const char *path, EAccessMode mode)
Returns FALSE if one can access a file using the specified access mode.
NB: for the time being mode is ignored for XROOTD (just checks existence
of the file or directory).
Mode is the same as for the Unix access(2) function.
Attention, bizarre convention of return value!!
