Previous works do not relate to function pointers, but reading some documents reading and learning STL functions lets me know the pointer of functions is broadly used in functions such as XXX_if(). I don't think it's really that difficult, but it rea…

C# unmanaged function pointers for iOS Just a reminder to myself when I need this thing next time for making Unity work with native code: delegate method should be static to please AOT compiler required for iOS method should have have [MonoPInvokeCal…

An simple example: #include<stdio.h> int plus(int a,int b) { return a+b; } int main() { int (*func)(int,int); func=&plus; //point to the function ''plus(int,int)'' printf(,)); ; } Another example: #include <stdio.h> #define MAX_COLORS 256…

Theory In the Java the function pointers is implemented by the declaring an interface to represent strategy and a class that implements this interface for each concrete strategy. It is possible to define an object whose methods perform operations on…

std::function 和 std::bind 标准库函数bind()和function()定义于头文件中(该头文件还包括许多其他函数对象),用于处理函数及函数参数.bind()接受一个函数(或者函数对象,或者任何你可以通过”(…)”符号调用的事物),生成一个其有某一个或多个函数参数被“绑定”或重新组织的函数对象.(译注:顾名思义,bind()函数的意义就像它的函数名一样,是用来绑定函数调用的某些参数的.)例如: int f(int, char, double); // 绑定f()函数调用的…
