The address of a function will always be visible in memory before it is called; however, by storing an obfuscated version of the function pointer, disassemblers and cross-reference analysis tools will fail to recognize the stored pointer as a code address. Note that this technique will not wor...
空指针,可能是某个参数没有默认值
C七:指向函数的指针 --- 函数指针(function pointer) 函数具有可赋值给指针的物理内存地址,一个函数的函数名就是一个指针,它指向函数的代码。一个函数的地址是该函数的进入点,也是调用函数的地址。函数的调用可以通过函数名,也可以通过指向函数的指针来调用。函数指针还允许将函数作为变元传递给其他函数。 不带括号...

The void pointer, also known as the generic pointer, is a special type of pointer that can be pointed at objects of any data type! A void pointer is declared like a normal pointer, using the void keyword as the pointer’s type:
What is a function pointer or pointer to function? A function pointer is similar to the other pointers but the only difference is that it stores the address of a function instead of a variable. In the program whenever required we can invoke the pointed function using the function pointer. So...
