In sfarsit vom prezenta programele principale.
Programului principal al serverului este dat in shms.cpp:
#include
#include
#include "shmmesaj.h"
#include "shmReadWrite.cpp"
#include "dir.cpp"
#include "shmparinte.cpp"
main() {
HANDLE shm, semafor, cerere;
Segment *segment;
fclose(stdin);
fclose(stdout);
shm = CreateFileMapping((HANDLE)0xFFFFFFFF, NULL, PAGE_READWRITE,
0, sizeof(Segment), "SegmentMemoriePartajata");
segment = (Segment*)MapViewOfFile(shm, FILE_MAP_WRITE, 0, 0,
sizeof(Segment));
segment->tip = 0;
segment->pid = GetCurrentProcessId();
semafor = CreateSemaphore(NULL, 1, 1000, "OcupaSegment");
cerere = CreateSemaphore(NULL, 0, 1000, "ExistaCerere");
parinte(segment, semafor, cerere);
// Prin specificul problemei noastre cuncrete, nu se va ajunge la
// instructiunile de mai jos. Le scriem totusi pentru exemplificare.
CloseHandle(cerere);
CloseHandle(semafor);
UnmapViewOfFile(segment);
CloseHandle(shm);
}
Sursa clientului este data in shmc.cpp:
#include
#include
#include "shmmesaj.h"
#include "shmReadWrite.cpp"
#include "shmfiu.cpp"
main() {
HANDLE shm, semafor, cerere;
Segment *segment;
shm = OpenFileMapping(FILE_MAP_ALL_ACCESS, TRUE,
"SegmentMemoriePartajata");
segment = (Segment*)MapViewOfFile(shm, FILE_MAP_WRITE, 0, 0,
sizeof(Segment));
semafor = OpenSemaphore(EVENT_ALL_ACCESS, TRUE, "OcupaSegment");
cerere = OpenSemaphore(EVENT_ALL_ACCESS, TRUE, "ExistaCerere");
fiu(segment, semafor, cerere);
CloseHandle(cerere);
CloseHandle(semafor);
UnmapViewOfFile(segment);
CloseHandle(shm);
