Access from MQ4 a dll function with: variable-argument lists

hi,

Anyone knows if this is possible: to import an dll function which uses as argument a: variable-argument lists

e.g. http://www.cplusplus.com/reference/clibrary/cstdio/vprintf/

int vprintf ( const char * format, va_list arg );

if so how would one do it?

Thanks

MJ
