Constructor & Destructor Documentation

scoped_signal_mask()

libexcept::scoped_signal_mask::scoped_signal_mask

(

sig_list_t

block_signals = sig_list_t()

)

This constructor blocks the specified block_signals and the destructor restores the flags as expected once the object is out of scope.

If the block_signals list is empty, then all the signals get blocked. This is particularly useful to start a new thread.

Parameters

[in]

block_signals

The list of signals to block or empty to block them all.

~scoped_signal_mask()

libexcept::scoped_signal_mask::~scoped_signal_mask

(

)

This function restores the signals as they were before the scoped_signal_mask was created.
