The C function returns the index with a 0 base. You have to add one to it to return the value in Fortran. See the last line of the Fortran binding for Waitany in MPICH.

Hi,
I'm trying to overwrite the weak symbol mpi_waitany_ (fortran symbol), but I get an error (the function doesn't seem to work since it returns an index of 0). Here is my code, any idea why it doesn't work?
void mpi_waitany_(MPI_Fint* count, MPI_Fint* array_of_requests, MPI_Fint* index, MPI_Fint* status, MPI_Fint* err) { MPI_Status cstatus; MPI_Status_f2c(status, &cstatus); MPI_Request* c_req = (MPI_Request*)malloc(sizeof(MPI_Request)*(*count)); int i; for(i=0;i<*count;i++) { c_req[i] = MPI_Request_f2c(array_of_requests[i]); } *err = PMPI_Waitany(*count,c_req,index,&cstatus); MPI_Status_c2f(&cstatus, status); for(i=0;i<*count;i++) { array_of_requests[i] = MPI_Request_c2f(c_req[i]); } free(c_req); }
Thanks!
