Warning Message: Undefined; Assuming extern returning int

[alanhomer]

Hi,

Have downloaded a code from the internet that was originally to be used on a UNIX machine, have ran in with Microsoft Visual C++ and although there are no errors, I have 7 warnings all with the same ending:

undefined; assuming extern returning int.

Is there a simple reason i'm missing for this?

Thanks

Compiler Warning (level 3) C4013
'function' undefined; assuming extern returning int

An undefined function was called. The compiler assumed an external function that returned an int type.

Make sure that the function name is spelled correctly. All external functions should be prototyped as extern


Note:Next time remember to post the code also

After the compiler warning....there will be a linker error if linker doesn't find that function
