A quick example:
First the source of the .dll, put it into dmcdll.c:

#include <windows.h>
#include "dmcdll.h"
BOOL APIENTRY DllMain(HANDLE hModule, DWORD  ul_reason_for_call, LPVOID 
lpReserved)
{
    switch (ul_reason_for_call)
    {
    case DLL_PROCESS_ATTACH:
    case DLL_THREAD_ATTACH:
    case DLL_THREAD_DETACH:
    case DLL_PROCESS_DETACH:
       break;
    }
    return TRUE;
}
__declspec( dllexport ) int DoSomething(int a, int b)
{
    return a*b*2;
}

Then a headerfile called dmcdll.h:
__declspec( dllexport ) BOOL APIENTRY DllMain( HANDLE hModule, DWORD 
ul_reason_for_call, LPVOID lpReserved);

__declspec( dllexport ) int DoSomething(int a, int b);

And a small test program called dmctest.c:

#include <stdio.h>
#include <windows.h>
#include "dmcdll.h"

int main()
{
    printf("Result: %d\n", DoSomething(12, 32));
    return 0;
}

Now we can build the dll with this command:
dmc -mn -WD dmcdll.c kernel32.lib

The we create a .lib from the .dll:
implib.exe /noi /system dmcdll.lib dmcdll.dll

And compile our test program, using the .lib:
dmc dmctest.c dmcdll.lib

Then you can run dmctest.exe, which with a bit of
lock should print:
Result: 768
