//structure contains function pointer typedef struct { int(*BasicCalculation)(void); int(*HouseRentCalculation)(void); int(*BonusCalculation)(void); int(*MedicalCalculation)(void); int TotalSallary; }sSallaryCa
I certainly may be missing something obvious, but there seems to be an issue with implementing a function pointer in a struct referenced by a pointer:struct MyStruct {void (*SetDriveMode)(uint8);};void Function1(const struct MyStruct * structPntr) {...
Unfortunately, it didn't work and the compiler is throwing its errors on an instruction that is attempting to call a function from a void pointer that is an element of a structure. Compiling the attached project gives the error at menu_struct.c line 44 (I have modified the project so ...
Function Pointers in C Just as a variable can be declared to be a pointer to an int, a variable can also declared to be a pointer to a function (or procedure). For example, the following declares a variable v whose type is a pointer to a function that takes an int as a parameter ...
pboy=struct_pass_by_address(&boy); 呼叫struct_pass_by_address() function,由於要傳進去的是pointer,所以必須&boy;因為傳回的也是pointer,所以使用pboy。 19行 pboy->no=10; strcpy(pboy->name,"oomusou"); 實際去改變struct值,因為傳進function的為pointer pboy,所以要用->,這是C的語法規定;另外C的...

在C语言中,初始化函数指针时遇到“incompatible function pointer types”错误通常意味着你试图将一个函数指针赋值给另一个不兼容类型的函数指针。具体到你的问题,错误提示是关于初始化void (*)(struct i2c_client)类型的函数指针。 分析错误原因 函数指针类型不匹配: 你可能有一个函数指针,其期望的类型是void (*)...
