#include "mpi.h" int MPI_Irecv( buf, count, datatype, source, tag, comm, request ) void *buf; int count; MPI_Datatype datatype; int source; int tag; MPI_Comm comm; MPI_Request *request;
| buf | initial address of receive buffer (choice) | |
| count | number of elements in receive buffer (integer) | |
| datatype | datatype of each receive buffer element (handle) | |
| source | rank of source (integer) | |
| tag | message tag (integer) | |
| comm | communicator (handle) | 
All MPI objects (e.g., MPI_Datatype, MPI_Comm) are of type INTEGERin Fortran.
