rt_sigprocmask (nr 14)

Linux Signature

int rt_sigprocmask(int how, const sigset_t *set, sigset_t *oldset, size_t sigsetsize);

Description

Examine and change blocked signals.

Current Implementation

Stub: Returns 0 (success) unconditionally. No signal support is implemented. musl’s runtime and posix_spawn call rt_sigprocmask to configure the signal mask; the stub allows this to succeed silently.
