18.2.282.2. DESCRIPTION

The fromint function translates a C integer to the appropriate C handle. Only an integer obtained from a previous call to MPI_Comm_toint, etc. may be passed to this function. It is erroneous to pass to this function an integer associated with a handle that has been freed, disconnected, or aborted (or that was derived from a session that has been finalized).

18.2.282.3. NOTES

These functions are only available in C; they are not available in any of the Fortran MPI interfaces.

These functions do not return an error value.
