I have very little assembler/x86 knowledge. Could anyone please help me understand what it means to assign a non-zero value to td_retval in a system call when return value of the call is zero/success?
I see in syscall() in src/sys/i386/i386/trap.c (btw is this the right place?) that in such circumstances value from td_retval[] is put into EAX and EDX registers and PSL_C (carry bit) is cleared in status/flags register in a stack frame of a calling process. But I don't understand what it practically means for the calling process. Thank you in advance. -- Andriy Gapon _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
