Dear All,
Next is question about "MPI_Close_port".
According to the MPI-2.2 standard,
the "port_name" argument of
MPI_Close_port() is marked as 'IN'.
But, in Open MPI (both trunk and 1.4.x), the content of
"port_name" is updated in MPI_Close_port().
It seems to violate the MPI standard.
The following is the suspicious part.
---ompi/mca/dpm/orte/dpm_orte.c---
919 static int close_port(char *port_name)
920 {
921 /* the port name is a pointer to an array - DO NOT FREE IT! */
922 memset(port_name, 0, MPI_MAX_PORT_NAME);
923 return OMPI_SUCCESS;
924 }
---ompi/mca/dpm/orte/dpm_orte.c---
This memset makes "port_name" "INOUT".
Would you tell me why call this memset?
