rt_sigaction (nr 13)

Linux Signature

int rt_sigaction(int signum, const struct sigaction *act,
                 struct sigaction *oldact, size_t sigsetsize);

Description

Examine and change a signal action.

Current Implementation

Stub: Returns 0 (success) unconditionally. No signal support is implemented. musl’s runtime init calls rt_sigaction to install default signal handlers; the stub allows this to succeed silently.
