variable block size, read only one block, read directly into user
supplied buffer, return ENOMEM if user supplied buffer is smaller
than size of next block to read. Use read2 instead of bytes_to_read
to count number of bytes read.
* fhandler_tape.cc (fhandler_dev_tape::open): Add debug output.
process struct pointer, which isn't fixed under Cygwin.
(semexit_myhook): Ditto. Adjust debug print statements to print
Cygwin and Windows PIDs instead of process pointer under Cygwin.
to force signal to be handled. Zero event here to prevent races.
* signal.cc (sigwaitinfo): Use local handle value for everything since signal
thread could zero event element at any time. Detect when awaking due to thread
not in mask and set return value and errno accordingly. Don't set signal
number to zero unless we've recognized the signal.
* sigproc.cc (sigq): Rename from sigqueue throughout.
* thread.cc (pthread::join): Handle signals received while waiting for thread
to terminate.
* cygwin.din: Export sighold, sigqueue.
* exceptions.cc (sighold): Define new function.
* signal.cc (handle_sigprocmask): Set correct errno for invalid signal.
Simplify debugging output.
(sigqueue): Define new function.
* include/cygwin/signal.h (sighold): Declare new function.
(sigqueue): Ditto.
* include/cygwin/version.h: Bump API minor version number.
* include/limits.h (TIMER_MAX): Define.
(_POSIX_TIMER_MAX): Ditto.
Add do_sig_wait parameter. Wait for signal_arrived if set to true.
Return WAIT_SIGNALED if signal arrived.
(pthread_cond::wait): Accomodate change to pthread::cancelable_wait.
(pthread::join): Ditto.
(semaphore::_timedwait): Ditto.
(semaphore::_wait): Ditto. Change to return int to allow status
feedback.
(semaphore::wait): Return return value from semaphore::_wait.
* thread.h (WAIT_SIGNALED): New definition.
(pthread::cancelable_wait): Change declaration. Define do_sig_wait
as false by default to not interfere with existing calls accidentally.
(semaphore::_wait): Declare int.
(copy1): New function.
(copyenc): New function.
(mount_item::fnmunge): Return error condition. Use new functions to copy
strings.
(mount_item::build_win32): Ditto.
(mount_info::conv_to_win32_path): Return error condition.
(cygwin_conv_to_posix_path): Return result of path conversion.
(cygwin_conv_to_full_posix_path): Ditto.
(return_with_errno): New macro.
(cygwin_win32_to_posix_path_list): Use new macro to potentially set errno.
(cygwin_posix_to_win32_path_list): Ditto.
* path.h (mount_item::fnmunge): Add size argument.
(mount_item::build_win32): Ditto.
