std::bind a static member function inside the class
13,305
The type of a pointer to static member function looks like a pointer to a non-member function:
auto storeFunc = std::bind ( (void(*)(WORD, WORD, double, bool))
&CSoundRouteHandlerApp::MakeRoute,
sourcePort, destPort, volume, true );
Here's a simplified example:
struct Foo
{
void foo_nonstatic(int, int) {}
static int foo_static(int, int, int) { return 42;}
};
#include <functional>
int main()
{
auto f_nonstatic = std::bind((void(Foo::*)(int, int))&Foo::foo_nonstatic, Foo(), 1, 2);
auto f_static = std::bind((int(*)(int, int, int))&Foo::foo_static, 1, 2, 3);
}

I am trying to store a function to call later, here is a snippet.
This works fine:
void RandomClass::aFunc( int param1, int param2, double param3, bool isQueued /*= false */ ) { /* If some condition happened, store this func for later */ auto storeFunc = std::bind (&RandomClass::aFunc, this, param1, param2, param3, true); CommandList.push( storeFunc ); /* Do random stuff */ }
However, if RandomClass is static, so I believe I should do this:
void RandomClass::aFunc( int param1, int param2, double param3, bool isQueued /*= false */ ) { /* If some condition happened, store this func for later */ auto storeFunc = std::bind (&RandomClass::aFunc, param1, param2, param3, true); CommandList.push( storeFunc ); /* Do random stuff */ }
But this doesn't work, I get the compile error
error C2668: 'std::tr1::bind' : ambiguous call to overloaded function
Any help appreciated.
