Usage Explanation

DosFreeModule frees the reference to the dynamic link module for this process and if the dynamic link module is not used by any other process the memory occupied by the module is freed. This means that no functions in the dynamic link module can be used any longer.

Sample Code

HMODULE hmod;
APIRET rc=0;

/* Load DLL with DosLoadModule */

/* Free DLL */
rc = DosFreeModule(hmod);
if(rc) {  /* Not success? */
   printf("Error. Cannot free the DLL. DosFreeModule returned %d.\n",rc);
   return(-1);
}
