hi!

everybody can tell me what are different between ccall and call, cinvoke and invoke

In some case i must use cinvoke, if i use "invoke" my application will crash
why?

thank for reply


sorry for my english

invoke, cinvoke, stdcall and ccall are macros to support calling conventions.

call is an assembler instruction supported by the CPU.

Use invoke for all Windows API calls except wsprintf (STDCALL)

Use cinvoke for all C library calls and wsprintf (CDECL)

Use ccall to call internal functions you have defined as CDECL compliant.

Use stdcall to call internal functions you have defined as STDCALL compliant.

The difference between invoke and stdcall is that invoke calls the address at the address you pass, and stdcall calls the address itself. invoke internally uses stdcall to call the address at an address(ie with []). The same is true for the two cdecl macros.

To give an illustration:


Like revolution said, if you want to call a label you use stdcall or its cdecl cousin. When calling a label, you use it without [].
