Typedef Documentation

typedef enum ErrMessage_t ErrMessage_t

Enumerated type listing valid error return values. All values except ERR_UNKNOWN and ERR_NONE have accompanying values in the string table ErrMessages[], for example ErrMessages[ERR_INVALIDINPUT] Referenced by main(), TMM_AllocateHeap(), TMM_EnablePaging(), TMM_Free(), TMM_FreeHeap(), TMM_PagedAllocateProcess(), TMM_PagedTerminateProcess(), TMM_ParseFilePtr(), TMM_ParseLine(), TMM_PrintAllMemory(), TMM_PrintFrames(), TMM_PrintHeap(), TMM_PrintInvertedPageTable(), TMM_PrintPages(), TMM_PrintPageTable(), TMM_PrintProcessMemory(), TMM_PrintProcessTable(), TMM_ReallocateHeap(), TMM_StoreHeapInteger(), TMM_StoreHeapString(), TMM_StoreInteger(), TMM_StoreString(), TMM_TerminateProcess(), and TMM_WatchPaging().

typedef struct InvPageTable InvPageTable

Info about each page #.

typedef struct ToyMM ToyMM

Structure that defines a Toy Memory Manager. Contains an array of pointers to processes(NULL denotes no process), an array of memory elements, a linked list of free space, and a member describing the size of the memory array.

ToyMM* TMM_Create (  int    memSize )

Creates a new Toy Memory Manager. See also: TMM_Free() Definition at line 466 of file ToyMem.c. References invPageTable, MAX_PROCESSES, mem, memFree, memSize, page, pageSize, processList, swap, TMM_CreateSegList(), ToyMem::type, and watchPaging. Referenced by main().

ErrMessage_t TMM_Free (  ToyMM *    tmm )

Frees a Toy Memory Manager. See also: TMM_Create() Definition at line 511 of file ToyMem.c. References ErrMessage_t, invPageTable, MAX_PROCESSES, mem, memFree, processList, TMM_FreeSegList(), TMM_PagedTerminateProcess(), TMM_PagingEnabled(), TMM_SwapDestroy(), and TMM_TerminateProcess(). Referenced by main().

int TMM_ParseFile (  const char *    fname, ToyMM *    tm )

Function to parse a commandfile. Definition at line 779 of file ToyMem.c. References TMM_ParseFilePtr(). Referenced by main().

int TMM_ParseFilePtr (  FILE *    fp, ToyMM *    tm, int    prompt )

Just like TMM_ParseFile, except Parses input from file pointer. if prompt is nonzero, a console prompt is printed to stdout before each line is read. Definition at line 712 of file ToyMem.c. References ErrMessage_t, PRINT_ERROR, and TMM_ParseLine(). Referenced by TMM_ParseFile().
