c - Porting "WINAPI" datatype from Windows to Linux -

i'm converting windows networking source code in c linux. in progress, see line, , don't know how convert :

dword winapi functiona(lpvoid lpparam) {  } 

i meet error when compile : expected initializer before "functiona"

i have add line of code :

typedef unsigned long dword; 

about winapi. don't pretty sure how change this. have change in 2 case:

#define winapi cdecl #define winapi __stdcall 

but still meet above problem. how can fix ? :)

winapi not datatype calling convention. linux can drop winapi alltogether or put in appropriate header file:

#define winapi
