Strange void pointer declaration

[Eddie Dean]

Never seen something like this before, maybe you can shed some light on it ?

void ( * pfOnReceive ) [B][U]( void )[/U][/B];

Its a void pointer for a function reference with void arguments?

Never seen the bold part before

 

[FvM]

It's a regular C function pointer definition.

FVM has given the right answer.

pfOnReceive is a function pointer whose return type and arguments are void.
