syntax question

[boon kian]

Hi I have some syntax question which is bothering me. Can someone pls explain to me what these codes means or where to find answer to question with regards to syntax ? (I have access to MSDN library but I am still unable to find a satisficatory answer from there) 1. BOOL BOAPI ShowMessage (int, int) what does this function syntax means ?? esp BOAPI is it a data type ? something to do with dll convention ?? 2. #typedef bool (TYPEOF_InitP) (int *a); what does this syntax means ?? does it mean let TYPEOF_InitP be a function that return bool and take in 1 int variable ?? PLease advise. Thank you !! bk

It's probably a calling convention such as __stdcall boon kian wrote: #typedef bool (TYPEOF_InitP) (int* a); Assuming the # is a typo, that still isn't legal AFAICT. If you meant typedef bool (*TYPEOF_InitP) (int *a); then that means TYPEOF_InitP is a function pointer, that can point to functions that take an int* parameter and return a bool. --Mike-- Ericahist | CP SearchBar v2.0.2 | Homepage | RightClick-Encrypt | 1ClickPicGrabber "That probably would've sounded more commanding if I wasn't wearing my yummy sushi pajamas."   -- Buffy

Hi Mike, Thank you. But i still have some doubts to clarify: BOOL BOAPI ShowMessage (int, int) is a function. So when u need to call the function, u would do a normal ShowMessage (1,2) rite ? But when you call the function am i rite to say that a BOAPI macro would run first follow by the ShowMessage function ? If not, when would the BOAPI macro runs or how is it been used? Sorry for my poor command of the c-language. Please advise. Thank you. bk (btw u are rite abt the # typo and the missing * could also be a typo from the original source)

Yes, it's a normal function, so ShowMessage( 1, 2) would "work". In this instance, I think it's more likely that BOAPI is a simple text substitution, to something like __stdcall, as Mike has already said. This makes the code look like this BOOL __stdcall ShowMessage(int, int) which just says how the stack is used in terms of pushing params and cleaning up. There is no additional code to be executed.
