C++ (Cpp) IsPtrAlign4 Examples

Example #1

File: SkValidatingReadBuffer.cpp Project: W3SS/skia

const void* SkValidatingReadBuffer::skip(size_t size) {
    size_t inc = SkAlign4(size);
    const void* addr = fReader.peek();
    this->validate(IsPtrAlign4(addr) && fReader.isAvailable(inc));
    if (!fError) {
        fReader.skip(size);
    }
    return addr;
}

Example #2

File: SkReadBuffer.cpp Project: molikto/Skia

const void* SkReadBuffer::skip(size_t size) {
    size_t inc = SkAlign4(size);
    this->validate(inc >= size);
    const void* addr = fReader.peek();
    this->validate(IsPtrAlign4(addr) && fReader.isAvailable(inc));
    if (fError) {
        return nullptr;
    }

    fReader.skip(size);
    return addr;
}

Example #3

File: SkValidatingReadBuffer.cpp Project: W3SS/skia

SkScalar SkValidatingReadBuffer::readScalar() {
    const size_t inc = sizeof(SkScalar);
    this->validate(IsPtrAlign4(fReader.peek()) && fReader.isAvailable(inc));
    return fError ? 0 : fReader.readScalar();
}

Example #4

File: SkValidatingReadBuffer.cpp Project: W3SS/skia

int32_t SkValidatingReadBuffer::readInt() {
    const size_t inc = sizeof(int32_t);
    this->validate(IsPtrAlign4(fReader.peek()) && fReader.isAvailable(inc));
    return fError ? 0 : fReader.readInt();
}

Example #5

File: SkValidatingReadBuffer.cpp Project: W3SS/skia

void SkValidatingReadBuffer::setMemory(const void* data, size_t size) {
    this->validate(IsPtrAlign4(data) && (SkAlign4(size) == size));
    if (!fError) {
        fReader.setMemory(data, size);
    }
}

Example #6

File: SkValidatingReadBuffer.cpp Project: W3SS/skia

uint32_t SkValidatingReadBuffer::getArrayCount() {
    const size_t inc = sizeof(uint32_t);
    fError = fError || !IsPtrAlign4(fReader.peek()) || !fReader.isAvailable(inc);
    return fError ? 0 : *(uint32_t*)fReader.peek();
}
