GCC has attributes with which you can tell the compiler about how a lot of things should be handled by the compiler. Among such attributes the below function attributes are used to define constructors and destructors in C language. These would only work under GCC. As there is no objects and...

创建对象失败后,最终会调用_objc_fatal输出"attempt to allocate object of class failed"创建对象失败。 到此就完成了callAlloc中hasCustomAWZ( )返回YES的情况。那么hasCustomAWZ( )函数返回NO,情况是怎么样的呢? 代码语言:javascript 代码运行次数:0
Most methods that resize aCArrayobject or add elements to it usememcpy_sto move elements. This is a problem becausememcpy_sis not compatible with any objects that require the constructor to be called. If the items in theCArrayare not compatible withmemcpy_s, you must create a newCArrayof ...
In Visual Studio .NET 2003, this class keeps a count of the number of CImage objects created. Whenever the count goes to 0, the function GdiplusShutdown is automatically called to release resources used by GDI+. This ensures that any CImage objects created directly or indirectly by DLLs are...

Use a lock to protect BitArray objects. The same methods can be safely called in separate threads as long as they are not accessing the same BitArray struct. Basics Constructor - create a new bit array of length nbits BIT_ARRAY* bit_array_create(bit_index_t nbits) Destructor - free ...
