signal_set_base::flags

Enumeration representing the different types of flags that may specified when adding a signal to a set.

enum flags

none: Bitmask representing no flags.
restart: Affects the behaviour of interruptible functions such that, if the function would have failed with error::interrupted when interrupted by the specified signal, the function shall instead be restarted and not fail with error::interrupted.
no_child_stop: Do not generate SIGCHLD when child processes stop or stopped child processes continue.
no_child_wait: Do not transform child processes into zombies when they terminate.
dont_care: Special value to indicate that the signal registration does not care which flags are set, and so will not conflict with any prior registrations of the same signal.
