info = TaoInitialize(int *argc,char ***argv,char *file_name,
char *help_message);
This command initializes TAO, as well as MPI, PETSc, and other packages
to which TAO applications may link (if these have not yet
been initialized elsewhere).
In particular, the arguments argc and
argv are the command line arguments delivered in all C and C++
programs; these arguments initialize the options database.
The argument file_name
optionally indicates an alternative name for an options file, which by
default is called .petscrc and resides in the user's home directory.
One of the last routines that all TAO programs should
call is
info = TaoFinalize();This routine finalizes TAO and any other libraries that may have been initialized during the TaoInitialize() phase. For example, TaoFinalize() calls MPI_Finalize()if TaoInitialize() began MPI. If MPI was initiated externally from TAO (by either the user or another software package), then the user is responsible for calling MPI_Finalize().
