STINNER Victor <victor.stin...@haypocalc.com> added the comment:
signalfd-4.patch: my more recent patch exposing signalfd(). It lacks a
structure to decode the bytes read from the signalfd file descriptor. Example
in ctypes (msg135438):
class signalfd_siginfo(Structure):
_fields_ = (
('ssi_signo', c_uint32), # Signal number
('ssi_errno', c_int32), # Error number (unused)
('ssi_code', c_int32), # Signal code
('ssi_pid', c_uint32), # PID of sender
('ssi_uid', c_uint32), # Real UID of sender
('ssi_fd', c_int32), # File descriptor (SIGIO)
('ssi_tid', c_uint32), # Kernel timer ID (POSIX timers)
('ssi_band', c_uint32), # Band event (SIGIO)
('ssi_overrun', c_uint32), # POSIX timer overrun count
('ssi_trapno', c_uint32), # Trap number that caused signal
('ssi_status', c_int32), # Exit status or signal (SIGCHLD)
('ssi_int', c_int32), # Integer sent by sigqueue(2)
('ssi_ptr', c_uint64), # Pointer sent by sigqueue(2)
('ssi_utime', c_uint64), # User CPU time consumed (SIGCHLD)
('ssi_stime', c_uint64), # System CPU time consumed (SIGCHLD)
('ssi_addr', c_uint64), # Address that generated signal
# (for hardware-generated signals)
('_padding', c_char * 46), # Pad size to 128 bytes (allow for
# additional fields in the future)
)
