- INHIBIT_
DELIVERY - Prevents the kernel from jumping the context to the signal trampoline, but otherwise has absolutely no effect on which signals are blocked etc. Meant to be used for short-lived critical sections inside libc.
- KEEP_
OLD - Alias’s memory region at
old_addresstonew_addresssuch that both regions share the same frames. - MAP_
FIXED - MAP_
FIXED_ NOREPLACE - MAP_
LAZY - For userspace-backed mmaps, return from the mmap call before all pages have been provided by the scheme. This requires the scheme to be trusted, as the current context can block indefinitely, if the scheme does not respond to the page fault handler’s request, as it tries to map the page by requesting it from the scheme.

WRITE - PTRACE_
EVENT_ ADDRSPACE_ SWITCH - Sent when current-addrspace is changed, allowing the tracer to reopen the memory file.
- PTRACE_
EVENT_ CLONE - Sent when a child is cloned, giving you the opportunity to trace it. If you don’t catch this, the child is started as normal.
- PTRACE_
EVENT_ MASK - PTRACE_
FLAG_ IGNORE - Special meaning, depending on the event. Usually, when fired before an action, it will skip performing that action.
- PTRACE_
FLAG_ MASK - PTRACE_
STOP_ BREAKPOINT - Stop on a software breakpoint, such as the int3 instruction for x86_64.
- PTRACE_
STOP_ EXIT - Stop just before exiting for good.
- PTRACE_
STOP_ MASK - PTRACE_
STOP_ POST_ SYSCALL - Stop after a syscall is handled.
- PTRACE_
STOP_ PRE_ SYSCALL - Stop before a syscall is handled. Send PTRACE_FLAG_IGNORE to not handle the syscall.
- PTRACE_
STOP_ SIGNAL - Stop before a signal is handled. Send PTRACE_FLAG_IGNORE to not handle signal.
- PTRACE_
STOP_ SINGLESTEP - Stop after exactly one instruction. TODO: This may not handle fexec/signal boundaries. Should it?

Functions§
- wcoredump
- True if status indicates a core dump was created.
- wexitstatus
- If wifexited(status), the exit status.
- wifcontinued
- True if status indicates the child continued after a stop.
- wifexited
- True if status indicates normal termination.
- wifsignaled
- True if STATUS indicates termination by a signal.
- wifstopped
- True if status indicates the child is stopped.
- wstopsig
- If wifstopped(status), the signal that stopped the child.
- wtermsig
- If wifsignaled(status), the terminating signal.
