NAME
MPI_T_finalize - Finalize the MPI tool information interface
SYNTAX
C Syntax
#include <mpi.h>
int MPI_T_finalize(void)
DESCRIPTION
MPI_T_finalize() finalizes the MPI tool information interface and must
be called the same number of times as MPI_T_init_thread() by the end of
execution. Calls to MPI tool functions are allowed at any point in exe-
cution as long as MPI_T_init_thread() has been called at least once and
the number of calls to MPI_T_init_thread() is greater than the number
of calls to MPI_T_finalize(). If at any point in execution the number
of calls to MPI_T_finalize() equals the number of calls to
MPI_T_init_thread() the MPI tool interface will no longer be available
until another call to MPI_T_init_thread().
NOTES
Before the end of execution the number of calls to MPI_T_init_thread()
and MPI_T_finalize must be the same.
ERRORS
MPI_T_finalize() will fail if:
[MPI_T_ERR_NOT_INITIALIZED]
The MPI Tools interface not initialized
