15ROOT top level object description.
16
17The TROOT object is the entry point to the ROOT system.
18The single instance of TROOT is accessible via the global gROOT.
19Using the gROOT pointer one has access to basically every object
20created in a ROOT based program. The TROOT object is essentially a
21container of several lists pointing to the main ROOT objects.
22
23The following lists are accessible from gROOT object:
24
25~~~ {.cpp}
26 gROOT->GetListOfClasses
27 gROOT->GetListOfColors
28 gROOT->GetListOfTypes
29 gROOT->GetListOfGlobals
30 gROOT->GetListOfGlobalFunctions
31 gROOT->GetListOfFiles
32 gROOT->GetListOfMappedFiles
33 gROOT->GetListOfSockets
34 gROOT->GetListOfSecContexts
35 gROOT->GetListOfCanvases
36 gROOT->GetListOfStyles
37 gROOT->GetListOfFunctions
38 gROOT->GetListOfSpecials (for example graphical cuts)
39 gROOT->GetListOfGeometries
40 gROOT->GetListOfBrowsers
41 gROOT->GetListOfCleanups
42 gROOT->GetListOfMessageHandlers
43~~~
44
45The TROOT class provides also many useful services:
46 - Get pointer to an object in any of the lists above
47 - Time utilities TROOT::Time
48
49The ROOT object must be created as a static object. An example
50of a main program creating an interactive version is shown below:
51
52### Example of a main program
53
54~~~ {.cpp}
55 #include "TRint.h"
56
57 int main(int argc, char **argv)
58 {
59 TRint *theApp = new TRint("ROOT example", &argc, argv);
60
61 // Init Intrinsics, build all windows, and enter event loop
62 theApp->Run();
63
64 return(0);
65 }

617/// Initialize the ROOT system. The creation of the TROOT object initializes
618/// the ROOT system. It must be the first ROOT related action that is
619/// performed by a program. The TROOT object must be created on the stack
620/// (can not be called via new since "operator new" is protected). The
621/// TROOT object is either created as a global object (outside the main()
622/// program), or it is one of the first objects created in main().
623/// Make sure that the TROOT object stays in scope for as long as ROOT
624/// related actions are performed. TROOT is a so called singleton so
625/// only one instance of it can be created. The single TROOT object can
626/// always be accessed via the global pointer gROOT.
627/// The name and title arguments can be used to identify the running
628/// application. The initfunc argument can contain an array of
629/// function pointers (last element must be 0). These functions are
630/// executed at the end of the constructor. This way one can easily
631/// extend the ROOT system without adding permanent dependencies
632/// (e.g. the graphics system is initialized via such a function).

2518 // *after* the construction of the TApplication object and thus
2519 // after the registration (atexit) of the EndOfProcessCleanups
2520 // routine. Consequently, after the end of main, libNet is
2521 // unloaded before EndOfProcessCleanups is called. When
2522 // EndOfProcessCleanups is executed it indirectly needs the TClass
2523 // for TSocket and its search will use resources that have already
2524 // been unloaded (technically the function static in TUnixSystem's
2525 // DynamicPath and the dictionary from libNet).
2526

2531 // load UserLibrary
2532 // create TFile
2533 // Append UserObject to TFile

2536

2538 // call EndOfProcessCleanups
2539 // Write the TFile
2540 // attempt to write the user object.
2541 // ....
2542
2543 // where what we need is to have the files closen/written before
2544 // the unloading of the library.
2545
2546 // To solve the problem we now register an atexit function for
2547 // every dictionary thus making sure there is at least one executed
2548 // before the first library tear down after main.
2549
2550 // If atexit is called directly within a library's code, the

2552 // after then end of main (whichever comes first). We do *not*
2553 // want the files to be closed whenever a library is unloaded via
