Why can't I forward declare myotherstruct? Jul 19, 2012 at 11:44am Need4Sleep(570) what error do you get? EDIT: whoops, didnt see Try this: 1 2 3 4 5 typedefstructmystruct {inti;doublef; } myotherstruct; Last edited onJul 19, 2012 at 11:47am ...
undefined C struct forward声明 在C语言中,forward声明是一种将结构体的定义推迟到稍后的代码中的方法。这种做法通常用于处理循环依赖或者在代码中避免使用嵌套结构体。 例如,如果你有两个结构体,它们之间存在循环依赖,你可以使用forward声明来避免编译错误。 代码语言:c 复制 // 声明而不是定义结构体 struct B; /...
Don't use that old C-style typedef stuff. Just declare the struct like this: struct STREAM { /* Used from v5.0 */ DWORD ID; /* unique ID of stream, remains unchanged in drawing */ DWORD VertxCount; /* Number of vertices on stream */ ...
typedef struct mbedtls_ecp_keypair MY_ECC_KEY. (This already works for some structs, like mbedtls_x509_crt) I think this would be useful outside my case as I imagine there are many applications that support mbedtls as well as another implementation, and being able to forward declare types ...
