Ensure that the global function with a few (up to some implementation-defined limit) is executed on scope exit, whether due to a normal function return or because an exception has been thrown.
A typical example of its usage:
void *buf = malloc(size);
#define wxON_BLOCK_EXIT1(function, p1)
Definition scopeguard.h:80

Include file:
#include <wx/scopeguard.h>
template<typename F , typename P1 , ... , typename PN >
Returns a scope guard object which will call the specified function with the given parameters on scope exit.
This function is overloaded to take several parameters up to some implementation-defined (but relatively low) limit.
The func should be a functor taking parameters of the types P1, ..., PN, i.e. the expression func(p1, ..., pN)
should be valid.
