    MockSyscallsManager::getInstance().resetAll();


    // Add a hook for fread()
    MockSyscallsManager::getInstance().setFreadHook(
      [](void *ptr, size_t size, size_t, FILE *) -> int {
        if (size == NPUBIN_META_SIZE)
        {
          auto meta = reinterpret_cast<npubin_meta *>(ptr);
          meta->program_size = 1024;
          meta->weight_size = 1024;
          meta->size = 4096;
        }
        return 1;
      });


    MockSyscallsManager::getInstance().setIoctlHook(
      [](int, unsigned long request, void *arg) -> int {
        // Get Version
        if (request == _IOR(0x88, 1, unsigned int))
        {
          // Return version 3.2.X.X for trix backend sanity checking
          *static_cast<int *>(arg) = 0x3020000;
        }
        return 0;
      });

Previous form of open() was,

int open(const char *, int, ...) { return 0; }

[batcheu]

The parameter 'mode' is only required when a file is created (O_CREAT).

[batcheu]

The previous definition of mmap() was,

void *mmap(void *, size_t, int, int, int, off_t) { return (void *)0x1; }

[batcheu]

The previous definition of munmap() was,

int munmap(void *, size_t) { return 0; }

[batcheu]

Previous definition of close(),

int close(int) { return 0; }

[batcheu]

Previous definition of ioctl(),

int ioctl(int, unsigned long, ...) { return 0; }

[batcheu]

Previous definition of fopen()

size_t fread(void *, size_t, size_t, FILE *) { return 1; }

[batcheu]

fclose() is newly added.

[batcheu]

Previous definition of fread()

size_t fread(void *, size_t, size_t, FILE *) { return 1; }

[batcheu]

Previous definition of fseek()

int fseek(FILE *, long, int) { return 0; }
