Here, thegetInformation()function is called usings = getInformation();statement. The function returns a structure of typestruct student. The returned structure is displayed from themain()function. Notice that, the return type ofgetInformation()is alsostruct student. ...
// that returns a pointer to a char typedef c d(); // d is a function returning // a pointer to a function // that returns a pointer to a char typedef d *e; // e is a pointer to a function // returning a pointer to a // function that returns a // pointer to a char e...
Now, functions in C can return the struct similar to the built-in data types. In the following example code, we implemented a clearMyStruct function that takes a pointer to the MyStruct object and returns the same object by value. Note that we need to access struct members using the ->...
// function that returns a // pointer to a char e var[10]; // var is an array of 10 pointers to // functions returning pointers to // functions returning pointers to chars. typedef经常用在一个结构声明之前,如下。这样,当创建结构变量的时候,允许你不使用关键字struct(在C中,创建结构变量时要...
Each of these functions returns a pointer to the first occurrence of strCharSet in string, or NULL if strCharSet does not appear in string. If strCharSet points to a string of zero length, the function returns string 1.这其实就是个字符串查找函数,如果在string中存在strcharset,则返回string中首...

This MATLAB function calls function funcname in C library libname, passing input arguments arg1,...,argN.
You cannot use this syntax in a MATLAB Function block. example outtype = coder.cstructname(intype,structName,'extern','HeaderFile',headerfile) returns a type object outtype that specifies the name and location of an externally defined C structure type. The code generator uses the externally ...
