I need to expose a C function to Matlab, which returns (among other things) a list of strings based on some inputs. As there are many returned values, I group them all under a struct. The structure is used as an in/out parameter, not a simple return value (which is used for ...
Pointer to data member of an accessible unambiguous non-virtual base class can beimplicitly convertedto pointer to the same data member of a derived class: structBase{intm;};structDerived:Base{};intmain(){intBase::*bp=&Base::m;intDerived::*dp=bp;Derived d;d.m=1;std::cout<<d.*dp<...
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 ...
C - returning a pointer to a 2d array, I am trying to write a getter for a 2d array of a struct. I have tried all kinds of solutions and my IDE complains about all of them. static history_t history[3][6]; history_t **get_history(){ return history; }; From my understanding, ...
The top-level complex structure skips the array marshaling. Unmarshaling, bufsizing and freeing passes Unmarshaling is symmetrical to marshaling; the first operation it performs for complex structures is to find out the pointees' location in the buffer by means of calling the NdrComplexStructBuffer...
warning: ‘struct tm’ declared inside parameter list will not be visible outside of this definition or declaration 直译过来是:警告:在参数列表中声明的“struct tm”在此定义或声明之外将不可见,实际上是这个struct tm编译器无法找到,多半是没有加头文件导致的,加上头文件即可 repo sync时...

Inside themainfunction, an object pointer*xis created from the structround. Lastly, the pointer object is called. Here, an incomplete struct is used as if it is a complete struct, which causes the compiler to throw the error. 1035906452/source.c: In function 'main':1035906452/source.c:6...

If I use plain (restrict annotated) pointer arguments for a kernel directly, the behavior is what I expect and what you described. Still, if I use restrict annotated pointers inside a struct, it’s compiling, but the compiler doesn’t seem to take advantage of this. ...
