Question

I have a c source file in which one of the method is defined as follows:

void QDECL prettyPrintf(int level) {
  ////// some code.
}

I would like to know what is QDECL.In this case, is it returning QDECL type? As far as my little knowledge in C, a ‘void’ does not return anything.So, is it a legal statement?

Answer 1

I just checked the definition of QDECL. It is

#define QDECL   __cdecl

Now your declaration becomes,

void __cdecl prettyPrintf(int level)

which is still a function which returns void.

In fact QDECL can still take ( theoretically ) some other forms without altering the return type of your function. It easily could have been

#define QDECL static

Now, your function prototype is

void static prettyPrintf(int level)

which is still a void returning function
