C synopsis

MPI_Request MPI_Request_f2c(MPI_Fint request);

Parameters

request

Description

This function does not have C++ or FORTRAN bindings. MPI_Request_f2c returns a C handle to a request. If request is a valid FORTRAN handle to a request, MPI_Request_f2c returns a valid C handle to that same request. If request is set to the FORTRAN value MPI_REQUEST_NULL, MPI_Request_f2c returns the equivalent null C handle. If request is not a valid FORTRAN handle, MPI_Request_f2c returns a non-valid C handle. The converted handle is returned as the function's value. There is no error detection or return code.

Errors

None.
