Print informations about MidiShare memory space.

void PrintMemInfo(void)
{
    printf("MidiShare memory :\n");
    printf(" free space  : %i cells\n", MidiFreeSpace());
    printf(" used space  : %i cells\n", MidiTotalSpace() - MidiFreeSpace());
    printf(" total space : %i cells\n", MidiTotalSpace());
}

MidiFreeSpace inhibits all interrupts during its execution. If the remaining space is very large MidiFreeSpace can take a long time to execute and may cause overrun errors with fast incoming Midi data.
