C++ struct sigaction
WebHandlers installed by the sigaction() interface can be installed permanently and a custom set of signals can be blocked during the execution of the handler. These signals will be unblocked immediately following the normal termination of the handler (but not in the event of an abnormal termination such as a C++ exception throw.)

WebFor example, if st_mode or st_uid is changed by another process by calling chmod (2) or chown (2), stat () might return the old st_mode together with the new st_uid, or the old st_uid together with the new st_mode . The fields in the stat structure are as follows: st_dev This field describes the device on which this file resides. WebSpecial behavior for C++: The behavior when mixing signal-handling with C++ exception handling is undefined. Also, the use of signal-handling with constructors and destructors is undefined. C++ and C language linkage conventions are incompatible, and therefore sigaction() cannot receive C++ function pointers.

WebIf an incoming signal is handled by a signal-handling function, sigsuspend () returns after the signal-handling function returns. The signal mask of the thread is restored to whatever it was before sigsuspend () was called, unless the signal-handling functions explicitly changed the mask. This function is supported only in a POSIX program. WebC++ Structures. Structures (also called structs) are a way to group several related variables into one place. Each variable in the structure is known as a member of the structure.. …

That should allow you to port your code easily to most unices (plural of unix), and still use sigaction () since it is part of POSIX.
