* include/cygwin/signal.h: New file. (also check in tlsoffsets.h, missed by previous checkin)
2003-11-29 05:01:09 +08:00
//;# autogenerated: Do not edit.
* cygtls.cc (_cygtls::reset_signal_arrived): New function. (set_signal_arrived::~set_signal_arrived): Use reset_signal_arrived to reset state. * exceptions.cc (sig_handle_tty_stop): Use WAIT_SIGNALED rather than assume we know the return from cancelable_wait. (_cygtls::interrupt_setup): Modify to allow calling when executing in non-cygwin code via sigdelayed. Always reset signal_arrived. * gendef: Throughout use start_offset rather than the completely wrong sizeof__cygtls. (_sigdelayed): Rewrite to avoid duplication when calling the signal handler. (sigreturn): Delete. * gentls_offsets: Define start_offset rather than sizeof__cygtls. * tlsoffsets.h: Regenerate.
