Using only typedef means that you name it that way. otherwise it'd be more or less anonymous. On the Microsoft Windows Software Development Kit (SDK) released for Windows Vista and later, SOCKADDR and SOCKADDR_IN typedef tags are defined for sockaddr and sockaddr_in structures as follows: typedef struct sockaddr { #if (_WIN32_WINNT < 0x0600) u_short sa_family; #else ADDRESS_FAMILY sa_family; #endif //(_WIN32_WINNT < 0x0600) CHAR sa_data[14]; } SOCKADDR, *PSOCKADDR, FAR *LPSOCKADDR; typedef struct sockaddr_in { #if(_WIN32_WINNT < 0x0600) short sin_family; #else //(_WIN32_WINNT The typedef keyword allows the programmer to create new names for types such as int or, more commonly in C++, templated types--it literally stands for "type definition". Typedefs can be used both to provide more clarity to your code and to make it easier to make changes to the underlying data types that you use. What is a type? In C this is done using two keywords: struct and typedef.

typedef struct git_commit git_commit;. Run. And c2nim will ignore these,leaves a lots of undefined error. In c code,it will use like this: #include

For example: typedef struct { int x, y; } Point; as opposed to: struct Point { int x, y; }; could be declared as: Point point; instead of: struct Point point; Even better is to use the following.
A struct in the C programming language (and many derivatives) is a composite data type (or record) declaration that defines a physically grouped list of variables under one name in a block of memory, allowing the different variables to be accessed via a single pointer or by the struct declared name which returns the same address. The struct data type can contain other data types so is used for

C语言中struct typedef 以及结构体指针用法. 忘了名字吧，: 终于有个能看明白的人了。。我感觉他应该也不太懂吧。 应该是： typedef struct _Student{ char a; struct _Student *stu; char *str; }Student; 应该只能这样吧， Usando typedef para redefinir structs. É muito frequente o uso de typedef para redefinir tipos como estruturas a fim de tornar os nomes mais curtos, desta forma podemos representar uma estrutura usando apenas seu sinônimo. Exemplo: typedef e struct typedef struct _iobuf FILE;.
This keyword, typedef typically employed in association with user-defined data types in cases if the names of datatypes turn out to be a little complicated or intricate for a programmer to get or to use within programs.
