Summary

The SIGACTION_RESTORE_ procedure restores the signal-handling state saved by a

previous call to the SIGACTION_SUPPLANT_ procedure. SIGACTION_SUPPLANT_

allows a subsystem (such as a shared run-time library) to take over signal handling

temporarily. SIGACTION_RESTORE_ restores the signal-handling state of the

process before the subsystem exits.

Parameters

error returned value

indicates the outcome of the call:

0D indicates a successful outcome.

-1D indicates an error. The reason for the error is given in the

errno variable:

FE_EFAULT The address in signal-buffer is invalid.

FE_EINVAL the content of the signal-buffer contains invalid data

or SIGACTION_SUPPLANT_ was not called.

Note. This procedure can be called only from native processes.
