I can't find any help for hooking this kind of functions for example

int sprintf ( char * str, const char * format, ... );

Such functions as those usually use the cdecl calling convention. Since it is the caller that cleans the stack, there can be any number of parameters. See MSDN's comparison of different calling conventions here.

The function I want to hook is not sprintf but it is very similar.

Use the parameters that you know are pushed onto the stack to deduce the total number of parameters there are.
