ENUM UTRACE_SIGNAL_A(9) utrace core API ENUM UTRACE_SIGNAL_A(9)
NAME enum_utrace_signal_action - disposition of signal
SYNOPSIS enum utrace_signal_action { UTRACE_SIGNAL_DELIVER, UTRACE_SIGNAL_IGN, UTRACE_SIGNAL_TERM, UTRACE_SIGNAL_CORE, UTRACE_SIGNAL_STOP, UTRACE_SIGNAL_TSTP, UTRACE_SIGNAL_REPORT, UTRACE_SIGNAL_HANDLER };
CONSTANTS UTRACE_SIGNAL_DELIVER Deliver according to sigaction.
UTRACE_SIGNAL_IGN Ignore the signal.
UTRACE_SIGNAL_TERM Terminate the process.
UTRACE_SIGNAL_CORE Terminate with core dump.
UTRACE_SIGNAL_STOP Deliver as absolute stop.
UTRACE_SIGNAL_TSTP Deliver as job control stop.
UTRACE_SIGNAL_REPORT Reporting before pending signals.
UTRACE_SIGNAL_HANDLER Reporting after signal handler setup.
DESCRIPTION This is encoded in the action argument and the return value for a report_signal() callback. It says what will happen to the signal described by the siginfo_t parameter to the callback.
The UTRACE_SIGNAL_REPORT value is used in an action argument when a tracing report is being made before dequeuing any pending signal. If this is immediately after a signal handler has been set up, then UTRACE_SIGNAL_HANDLER is used instead. A report_signal callback that uses UTRACE_SIGNAL_DELIVER|UTRACE_SINGLESTEP will ensure it sees a UTRACE_SIGNAL_HANDLER report.
