Good question, but I don't think so. The first few lines of assembly from this function seem to read three arguments you see: 44b360: 53 push %rbx 44b361: 41 54 push %r12 44b363: 41 55 push %r13 44b365: 48 89 fb mov %rdi,%rbx <-- first argument, %rdi 44b368: 41 89 f4 mov %esi,%r12d <-- second argument, %rsi 44b36b: 49 89 d5 mov %rdx,%r13 <-- third argument, %rdx What I forgot to mention was that this is on a x86_64 architecture, so I based myself on the table found at http://wiki.osdev.org/Calling_Conventions . -- Ewald _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
