Function documentation

TNetXNGFile(const char* url, Option_t* mode = "", const char* title = "", Int_t compress = 1, Int_t netopt = 0, Bool_t parallelopen = kFALSE)

 param url:          URL of the entry-point server to be contacted
 param mode:         initial file access mode
 param title:        title of the file (shown by ROOT browser)
 param compress:     compression level and algorithm
 param netopt:       TCP window size in bytes (unused)
 param parallelopen: open asynchronously
void Init(Bool_t create)
 Initialize the file. Makes sure that the file is really open before
 calling TFile::Init. It may block.
Long64_t GetSize() const
 Get the file size. Returns -1 in the case that the file could not be
Bool_t IsOpen() const
 Check if the file is open
void SetAsyncOpenStatus(TFile::EAsyncOpenStatus status)
 Set the status of an asynchronous file open
void Close(const Option_t* option = "")
 Close the file

 param option: if == "R", all TProcessIDs referenced by this file are
               deleted (is this valid in xrootd context?)
Int_t ReOpen(Option_t* modestr)
 Reopen the file with the new access mode

 param mode: the new access mode
 returns:    0 in case the mode was successfully modified, 1 in case
             the mode did not change (was already as requested or wrong
             input arguments) and -1 in case of failure, in which case
             the file cannot be used anymore
Bool_t ReadBuffer(char* buffer, Int_t length)
 Read a data chunk of the given size

 param buffer: a pointer to a buffer big enough to hold the data
 param length: number of bytes to be read
 returns:      kTRUE in case of failure
Bool_t ReadBuffer(char* buffer, Long64_t position, Int_t length)
 Read a data chunk of the given size, starting from the given offset

 param buffer:   a pointer to a buffer big enough to hold the data
 param position: offset from the beginning of the file
 param length:   number of bytes to be read
 returns:        kTRUE in case of failure
Bool_t ReadBuffers(char* buffer, Long64_t* position, Int_t* length, Int_t nbuffs)
 Read scattered data chunks in one operation

 param buffer:   a pointer to a buffer big enough to hold all of the
                 requested data
 param position: position[i] is the seek position of chunk i of len
 param length:   length[i] is the length of the chunk at offset
 param nbuffs:   number of chunks
 returns:        kTRUE in case of failure
Bool_t WriteBuffer(const char* buffer, Int_t length)
 Write a data chunk

 param buffer: the data to be written
 param length: the size of the buffer
 returns:      kTRUE in case of failure
void Flush()
void Seek(Long64_t offset, TFile::ERelativeTo position = kBeg)
 Set the position within the file

 param offset:   the new offset relative to position
 param position: the relative position, either kBeg, kCur or kEnd
Int_t ParseOpenMode(Option_t* in, TString& modestr, XrdCl::OpenFlags::Flags& mode, Bool_t assumeRead)
 Parse a file open mode given as a string into a canonically formatted
 output mode string and an integer code that the xroot client can use

 param    in:         the file open mode as a string (in)
          modestr:    open mode string after parsing (out)
          mode:       correctly parsed option mode code (out)
          assumeRead: if the open mode is not recognised assume read (in)
 returns:             0 in case the mode was successfully parsed,
                     -1 in case of failure
Bool_t IsUseable() const
 Check the file is open and isn't a zombie
Bool_t GetVectorReadLimits()
 Find the server-specific readv config params. Returns kFALSE in case of
 error, kTRUE otherwise.
void SetEnv()
 Map ROOT and xrootd environment variables
TNetXNGFile(const char* url, Option_t* mode = "", const char* title = "", Int_t compress = 1, Int_t netopt = 0, Bool_t parallelopen = kFALSE)
TString GetNewUrl()
{ return fNewUrl; }
