标签: function-pointers Python ctypes和函数指针 这与我的另一个问题有关,但我觉得我应该在一个新问题中提出这个问题. 基本上FLAC使用函数指针进行回调,并使用ctypes实现回调,您可以使用CFUNCTYPE它们进行原型化,然后使用该prototype()函数创建它们. 我遇到的问题是我想我会创建我的回调函数(我没有显示我重新创建的...

Note the use of void*s to allow qsort to operate on any kind of data (in C++, you'd normally usetemplatesfor this task, but C++ also allows the use of void* pointers) because void* pointers can point to anything. Because we don't know the size of the individual elements in a void...
This commit addsvalueLocationReferenceto function pointers and function references. Thereby, users can navigate directly to the pointed-to function from within the "variables" pane. In general, it would be useful to also a add similar location references also to member function pointers,std::source...

For a project such as CPython, which has long relied on function pointers for callbacks, yet seems to have only required that callbacks behave as expected under typical ABI calling conventions, rather than more strictly be declared/defined as a type compatible with the function pointer they will...
Functors Compared with Function Pointers If you have a function that takes a function pointer, you cannot pass in a functor as though it were a function pointer, even if the functor has the same arguments and return value as the function pointer. ...
This code uses several C function pointers, but essentially the block of code which matches MOVEBOID indicates that the server-side procedure to call is moveboid_1, and that the relevant XDR routine for the arguments is xdr_boid_call and for the return value it is xdr_boolean. Below the ...
For this reason, a discussion of their properties is proposed in Annex B, in particular explaining how function objects can replace pointers to functions, with extended capabilities. In a function object, the name of the object can be used as a function name, and the member function called ...
