MPI_Comm_toint(3) MPI MPI_Comm_toint(3) NAME MPI_Comm_toint - converts MPI_Comm to an integer handle SYNOPSIS int MPI_Comm_toint(MPI_Comm comm) INPUT PARAMETERS comm - communicator (handle) THREAD AND INTERRUPT SAFETY This routine is thread-safe. This means that this routine may be safely used by multiple threads without the need for any user-provided thread locks. However, the routine is not interrupt safe. Typically, this is due to the use of memory allocation routines such as malloc or other non-MPICH runtime routines that are themselves not interrupt-safe. 4/10/2026 MPI_Comm_toint(3)
