 * UNIX signal support for main loops. In contrast to other

31
 * main loop event sources such as timer and IO events, UNIX signal

32
 * support requires modification of the global process

33
 * environment. Due to this the generic main loop abstraction layer as

34
 * defined in \ref mainloop-api.h doesn't have direct support for UNIX

35
 * signals. However, you may hook signal support into an abstract main loop via the routines defined herein.
